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 during your period. 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.

Implantation bleeding or period? How can you tell?

When does implantation bleeding occur?

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. If the bleeding is more than 14 days after your last sexual act, it’s unlikely to be implantation.

What does implantation bleeding look like?

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.

How common is implantation bleeding?

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.

Whether after reading this page or taking our implantation bleeding quiz you feel you’ve experienced implantation bleeding or not, 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.

I had sex with a girl on February 15th — did so unprotected, but I don’t necessarily remember producing pre-cum or anything and wasn’t anywhere close to her vagina during orgasm. A day later, her period started. Two weeks later (I think almost exactly), she was feeling emotional and all — she took a pregnancy test and it came back negative. A week or so later, she had bleeding which I initially thought was period blood but she told me it was bleeding related to her PCOS.

Can she still be pregnant?


So, I had sex on March 14, and the condom came off inside of me. He ended up cumming inside of me. This was the day before my predicted ovulation. The morning of the 15th, I took a Plan B, but then for two days I had clear/watery discharge almost like I was ovulating. Fast forward 7 days after taking Plan B (8 days after intercourse) on march 22, I started having a small amount of light pink spotting followed by nausea and headaches. The discharge changed to light brown/watery discharge for two days after that. My period is due… Read more »
