Implantation Bleeding Quiz: Implantation Bleeding or Period? 2259

Regardless of whether or not you’re trying to become pregnant or hoping you aren’t pregnant, the question implantation bleeding or period  is rather important. This raises another important question, just how do you tell: implantation bleeding or period?

What is implantation bleeding?

Implantation bleeding is bleeding that occurs as a result of a fertilized egg implanting in the uterine wall. This bleeding is the first recognizable sign of pregnancy and does not occur in all cases.

What is menstrual bleeding?

While most women already know what a period is, just for knowledge’s sake, a menstrual cycle is on average 28 days in length, but may vary from woman to woman. In this time, an egg should be released (about mid-way through your cycle), if the egg is fertilized it implants in the uterine wall and implantation bleeding may occur, if it’s not fertilized this egg travels on and is shed with the uterine lining. If you don’t release an egg, your period may be delayed, but you will likely still experience bleeding. Ovulation, or the release of this egg, can be confirmed by charting your basal body temperature.

Now that you understand what both are, let’s talk about how you can tell them apart. If you prefer, you’ll find a start button below to take our implantation bleeding quiz for a quick answer on the likelihood of your bleeding being implantation. Otherwise, beyond the implantation bleeding quiz start button you can read about the methodology used in this quiz in regards to telling implantation bleeding from a period. (jump to explanation)

Implantation bleeding or period? How can you tell?


Implantation bleeding will generally occur 6 to 12 days after intercourse or ovulation so pay attention to when your period should be and when this mysterious bleeding occurs. If you experiencing bleeding sightly earlier than you should, this could be a sign of implantation bleeding.

Implantation blood is usually a different color than your average menstrual blood being either darker and more brown (old blood) or lighter and pinkish (very new, light bleeding). Given the implanting egg is the size of a pinhead, implantation bleeding is very light and shorter in duration than your regular cycle– unless of course you don’t normally have one. Implantation usually just appears as just the faintest pink showing up on toilet paper when you use the bathroom or even just one to two tiny spots of blood. Implantation will not cause heavy bleeding, however, there are other ways one can be pregnant and still experience period-like bleeding. Some women also get a slight hormone dip at implantation that can cause both a temperature dip on basal body charts and possibly some light spotting. This type of bleeding is not a heavy flow.

Keep in mind that only about one third of women experience implantation bleeding. If you suspect pregnancy or have had unprotected sex, don’t assume that you’re not pregnant simply because you didn’t experience this symptom. Some women become pregnant and exhibit no symptoms what so ever.

Despite our implantation bleeding or period explanation and implantation quiz, a pregnancy test will always be the best way to ease your mind. Be sure to take the test after your regular period should have been and not immediately after the bleeding. Even if it is implantation bleeding, a pregnancy test will probably still read negative as hCG levels will be insufficient. On average it takes about 48 hours to get even a faint positive test.

    My partner recently had a vasectomy, his first sperm batch after the op came back positive then weeks later his second sample came back as containing no sperm & fine to use no contraceptive, so we used no contraceptive & now my period is a week late. Today have slight cramps & a spot of light very faint blood. I am really concerned. I am 43 & we dont want babies. So now also with faintest blood makes me think it could be implantation bleeding & would not get accurate result if I did pregnancy test? Please h-e-l-p !!!

      Your test would be accurate, but with him having a vasectomy and you being 43, the more likely culprit here is menopause.

    I am 4 day late for my period…today i seen some brownish colored blood in my underwear and when i wiped…not sure what is going on. My periods are regular and i usually start the night before i am suppose to start.

      I would bet you’ll see a period soon. Brown spotting is pretty common before a period. Lifestyle changes are often to blame for small cycle changes like this.

    Hi my period was late and I got it now but it’s stupid light because usually I have a heavy flow but now it’s light and when I while it’s light pink. But it also came with white discharge. Does that mean I could be pregnant?

      A late bleed is unlikely to implantation unless you ovulated late. It is, however, considered normal to have an occasional light cycle. It also being late may indicate a little bit of hormonal flux. Often lifestyle changes are to blame there (diet/exercise/sleep/stress/etc).
