Am I Pregnant? Calculate Your Chances of Being Pregnant 594


Let’s start out by getting this out of the way, no one, in the whole wide world, can tell you whether you are or are not pregnant over the Internet. I can’t. A quiz can’t. Scrutinizing timing and symptoms can’t. Google can’t. The only way to confirm a pregnancy is in person via examination, urine, or blood testing. Regardless, I get a ton of comments here at Gremlins asking, ”could I be pregnant?” or “am I pregnant?” So, that leaves us at what can I tell you? I mean I’ve responded to 1,000+ comments on the subject, and I’ve had something to tell them all.

The quiz linked above uses the information on this page. It’s still recommended you read below to understand your results.

How do you know if you’re pregnant?

When I respond to comments asking am I pregnant this I what I consider, my steps to calculating your chances of being pregnant….

The first factor you want to consider is timing. When was:

-Your last period
-The date of intercourse
If you know, the date of ovulation is also quite useful. You can find a full guide to pinpointing ovulation here.

Understanding when you can get pregnant helps a great deal in figuring out your chances of pregnancy. It is possible to become pregnant from intercourse at any time if you happen to be ovulating or ovulate while semen is still viable, but the chances are significantly higher during your fertile period. When is that? For most women, ovulation lands around mid-cycle. So, if your period is on average 28 days, ovulation is likely around the 14th day with day 1 being the first day of period bleeding. Note I said most. Not all women ovulate mid-cycle, and ovulation does fluctuate slightly each cycle for some. You can help guess when you are ovulating by paying attention to vaginal discharge. When you are fertile it will become more plentiful and watery. At ovulation itself, you may see egg-white-like discharge, sort of like clear snot (I know lovely imagery here.) There are also ovulation test strips you can buy if you are ttc, and basal body temping can also be a huge help.

Keep in mind that the egg survives on average 48 hours, and sperm is most viable within a 48-hour period. Sperm, however, can survive in the body for 5 or more days (studies differ on the subject).

Let’s consider some scenarios with that then.

Early intercourse: Can you get pregnant on your period?

The chances of pregnancy are low with intercourse during your period, but not impossible—remember up there where I said if there is intercourse, pregnancy is always possible. How can you get pregnant on your period? Well, because sperm can survive beyond that ideal 48-hour window, if you ovulate on the early side, it could still be around to catch the egg. It’s a scenario where the stars really have to align just right so to speak.

Ex/ 26 day cycle, 6 days active bleeding, early ovulation at day 10 (I actually had these stats when I got pregnant with baby 4) Intercourse on CD (cycle day) 5 during period, sperm can still be viable at 5+ days when the egg drops.

This, obviously, also applies to the question can you get pregnant right after your period as well, more so actually, because you are closer to mid-cycle.

Late intercourse: Can you get pregnant right before your period?

The chances of getting pregnant just before your period are lower, because while sperm can hang on quite some time in the vaginal canal, the egg is a bit more delicate. Most studies put viability at about 24 to 48 hours before it’s long gone. In this case, that means to become pregnant just before your period, you would need to ovulate quite late.

Ex/ 26 day cycle, Ovulation CD 22, Intercourse on CD 23, egg survives CD 22-23.

It would be nigh impossible to catch the following cycle’s egg this way, if you are wondering. Why? Even if intercourse was on CD 26 just before the period began, with a low probability 5-day survival you would still be looking at CD 5 for ovulation, which is very, very early, and questionably biologically possible.

Both of the above situations have a low chance of pregnancy, so what has a high chance?

Mid-cycle Intercourse: The ideal time for pregnancy

The closer to mid-cycle the intercourse is, the higher the chance of pregnancy. In general, because ovulation does fluctuate, anything after about CD9 and about a week before the end of your cycle can be considered a fertile period.

Ex/ 26 day cycle: fertile period from CD 9 to CD 19. Peak (ovulation) probable at CD 12-14

It should be kept in mind that the average couple ties for 6 months to conceive, and it’s estimated that there is only a 25 percent chance of pregnancy with a single sexual act during a fertile time. Sex mid-cycle does not guarantee pregnancy, it just poses the highest chance.

Side note, what if you don’t get periods?

Just because you aren’t having a menstrual period doesn’t necessarily mean you also aren’t ovulating. It’s entirely possible you just have very long cycles. Most women who don’t get periods, do have occasional bleeding. Lack of menstruation can mean you aren’t ovulating or it can mean you just aren’t doing so regularly. Either way, this is something you should speak with a care provider about as it is often indicative of an underlying condition.

Next, let’s talk about symptoms.

I’m going to come right out and say I don’t consider them at all. They are irrelevant this early, but then, I do have a quiz on early symptoms of pregnancy here, so why the hypocrisy there? You will not have pregnancy symptoms before you are pregnant. Period. This falls back in to timing. After sperm meets egg, it takes 6-12 days for that fertilized egg to find its way to the uterus and implant, it takes another 48 hours on average for pregnancy hormones to get high enough to even start to be detectable—that’s 8 to 14 days after fertilization which could be up to 48 hours after ovulation. Until that egg implants, you aren’t pregnant. There are no pregnancy hormones, your symptoms aren’t pregnancy related. I have a pregnancy symptom quiz, yes, but with big warnings all over it that it applies after a missed period (which for most is about 14 days after ovulation).

You may now be thinking to yourself, puh, this lady don’t know Jack or his sister Sally’s ovaries, because I had pregnancy symptoms before my last pregnancy. The thing is one of the major players in all those fun pregnancy side effects is progesterone, and progesterone is actually present in the body before pregnancy. Its production is super-charged by ovulation, and its purpose is to maintain a pregnancy. So, if you don’t get pregnant, it drops, and you get a period, if you do, it continues to rise. A high progesterone cycle will mimic the symptoms of pregnancy from nausea to gas. Pregnancy symptoms are basically PMS on steroids.

Down to the details….

Next, I look at the specifics. Not everyone wants a baby. Sometimes people are commenting desperately hoping I’ll say, “Hah, fat chance. You aren’t pregnant.” There are some common situations that decrease fertility and reduce the chances of pregnancy even if it’s mid-cycle.

I was on birth control when we had sex, can I be pregnant?

No method of birth control outside of not having sex offers 100 percent protection. Most forms are pretty dependable if carried out properly, we’re talking in the 90ish percentile, but even if there was a condom or birth control, it is still possible to become pregnant, the chance is just very small.

What if the condom fell off, broke, or came off inside of me?

Condoms break, slip off, and though it may be embarrassing to admit sometimes even come off inside of women. In all of the above cases, it is possible sperm escaped and pregnancy could occur. Plan-B or the morning after pill are usually a good idea in this circumstance, as well, chances or pregnancy are a lot higher than if the condom had stayed on.

He pre-ejaculated without protection, can that cause pregnancy?

Yes. Pre-cum (the liquid that sometimes precedes a true ejaculation) does sometimes contain sperm and can result in pregnancy. A man has no control over pre-ejaculation. This is why the pull-out method of birth control can fail and a condom should not just be used for ejaculation, but also during the entire sexual act if condoms are your primary source of birth control.

Can I get pregnant from masturbation with another, anal sex, or dry humping?

This comes down to two variables. In all three situations, what matters is if there was semen involved and if it touched your vagina. Even if there is no penetration involved in the sex, if semen comes in contact with your vagina on fingers, clothing or any other object, pregnancy can occur. The chances in this case, are again, decreased, if clothing was involved the chance of pregnancy is even lower, nigh on nonexistent, but not impossible. If there was no semen, or precum, there is no chance of pregnancy.

We had sex in water, am I pregnant?

While sperm can survive in water for a short time, unless the ejaculation occurred within your body, chances are very slim you are pregnant. If the semen was inside of you, the sex being within water will have no effect on your chances of pregnancy.

After you take all of the above into consideration, you should be able to calculate your own chances of getting pregnant– or being pregnant for that matter– to answer the question am I pregnant.

    Hi! So I have been on the pill called mononessa. It’s a 28 day pill. I’ve been on it for 4 months now. I’m currently on the progesterone pills or the period pills and tomorrow is my last day of taking those. Last Wednesday and Thursday I took both pills later than I was suppose to but I took them as soon as I remembered. Sunday I had sex 3 times with my boyfriend and he ejaculated in me all 3 times. I was suppose to take my pill around 6:15 but forgot and took it at like 7:15 or 7:30. My period started on Tuesday instead of Thursday which I assumed was from taking my pills late. I’ve been having a pretty medium to heavy period but we’ve still been having sex. He ejaculated in me the other day but other than Sunday those are the only times he’s ejaculated in me. Is it possible that I’m pregnant even though I’m on period? Thanks in advance!

      With the combination pill your chances of pregnancy are somewhere below around 3%. Taking your pill a few hours late would have little affect there, it’s missing days that can cause problems.

  • e.g

    Hi so my boyfriend and I had sex, not really sex but still. He broke my hymen, and pulled out right away. I was worried cause I was overreacting and had my period for the regular time. My only problem was it was a lot less blood then I normally have. Im about to have another period but is there even the smallest chance that I could be pregnant? Lately I have been feeling nauseous randomly until I eat. I just got back from a trip so maybe its that and my mom feels like me and people we were with felt a tad bit sick. My boyfriend told me to stop worrying and everything will be fine but I need to know. agh.

    • Life with Gremlins admin

      No, there’s no chance of pregnancy if he just stuck it in and took it out unless there was semen on his penis. Assuming you are a teen, occasional cycle changes and symptoms of hormonal imbalance are entirely normal. For most women hormones stay in flux until around age 19.

  • Zoie

    I had sex both saturday oct 7and sunday oct 8 both times we did not use a comdom. The first time he pulled out but barely coukd see where the cum went so im nervous now because it was barely to nowhere to be found. Second time he pulled out he cummed imediatley as soon as he did and im nervous he may have inside a little as well so im extremely nervous. My period was due to be on oct 12 but Ichabent gotten it yet and im having my normal period syptoms (back pain, hunger, ect) is that good ?

    • Life with Gremlins admin

      Seeing PMS wouldn’t affect whether or not you were pregnant, no. Regular period variance is +/-3 days though, so I wouldn’t worry just yet. If your period was due the 12th, and you had sex Oct 7/8 it sounds very unlikely you were fertile (being at the very end of your cycle). Pregnancy is very, very unlikely.

  • Jackie

    Hi so me and my boyfriend had unprotected sex on Saturday October 7 , 2017 ( condom broke) my last period started on September 14 ,2017 and ended around September 18-20 I do not remember anyways after the deed I took plan b about 12 hours later , could I be pregnant ? I don’t know when I ovulated and I haven’t gotten my period yet

    • Life with Gremlins admin

      It sounds like intercourse was around cycle day 23, assuming you run around a 28-day cycle (between day 1 bleeding and day 1 bleeding) you likely ovulated at day 14, well before the condom break. As a result there was no chance of pregnancy to begin with. Plan B also would not have stopped ovulation, but because it’s hormone based, it will cause some hormonal imbalance, late period and/or irregular bleeding included.

      • Jackie

        Thank you for replying I really hope I am not pregnant and I remember on September 29 I had clear stretchy discharge is this ovulation ? & does ovulation only happen for one day ? & does this bit of information mean I could get pregnant ?????

        • Life with Gremlins admin

          At ovulation you’ll see stretchy, clear discharge, yes, many women describe it as like egg whites. Ovulation itself occurs on 1 day, the egg remains viable for 24-48 hours after it’s released. Sperm can also survive around 5 days. This is why most apps give you a “fertile period,” not just one day. It’s a span from about 5 days before ovulation to 48 hours after.

          • Life with Gremlins admin

            Correct, not without late ovulation, which would have delayed your period by about a week and you would have seen signs of ovulation such as the discharge on the 7th.

          • Jackie

            Thank you for answering ! & I have been feeling like If period is coming out but when I check there is nothing my vagina just feels moist almost dry but it left a stain on my underwear not a white stain but just like if it was wet , what could this be ? Also I’m sorry to be replying to this comment , I did not see the option where I could reply to your most recent comment

          • Life with Gremlins admin

            It sounds like cervical mucus. Mucus varies throughout your cycle depending on hormone levels. It starts off dry and sticky, moves to watery and thin (probably what you’re seeing), peaks with fertility at egg white, and then tends to cycle back down through those stages to dry. Some women see heavier mucus discharge just before a period as well.

    • Life with Gremlins admin

      Yes, it sounds like your intercourse was from day 11 to 15, assuming you run a 28-day cycle, you likely ovulated on day 14, so yes, pregnancy is very possible (you were in the highest possible range for pregnancy). The average healthy couple with intercourse at ovulation (a single act) has around a 25% chance of pregnancy. You had multiple acts, so your chances may be a bit higher.

    Hi, my boyfriend and I had sex on the 7th of October and he came inside of me twice. My fertile days are the 7th, 8th, 9th, I ovulate either the 11th or 12th, sometime around there. Is it possible to get pregnant from him cumming inside but me not ovulating until the 11th? Please, I just need to learn amap. Can you get pregnant before ovulation?

    • Life with Gremlins admin

      The reason you’re considered fertile before ovulation is that sperm can survive in the body for up to 5 days and fertile cervical mucus (that which proceeds ovulation) is a lot more friendly to those sperm. Sperm is most viable (posing the highest risk of pregnancy) within the first 48 hours though. There’s also that ovulation can vary slightly from month to month. Without basal body tracking or ovulation prediction strips, there’s no way to guarantee you ovulated mid-cycle exactly. Most women do flux within a day or two each month.

      That being said, assuming you did ovulate the 11th, that was 4 days after the intercourse, so pregnancy is possible, but the chance is going to be lower than if it had been within 48 hours (so less than a 25% chance, but a chance.)

  • Alys

    I had unprotected sex on Thursday night (oct. 5th) but he didn’t cum inside of me. My period was supposed to start yesterday (oct. 8th) but it hasn’t started yet. It’s sometimes a day or two late but of course I’m paranoid. The last day of my last period was September 12th. I don’t know when I ovulated. Could I be pregnant?

    • Life with Gremlins admin

      Normal period variance is +/-3 days (this is just a result of normal hormone fluctuation from cycle to cycle). I wouldn’t worry until you are at least 4 days late. If your last period began Sept 12, your intercourse was on day 24. It would be highly unusual to be fertile that late in your cycle unless you run a very long or irregular cycle normally. Basically, pregnancy isn’t entirely impossible (nothing is), but it’s pretty close to it.
