Can you have implantation bleeding three days after you have ovulated?

That seems a bit early to me, but it is probably possible. Although I'm not sure how you know when you ovulated, unless you are testing yourself regularly. Wait another day or two and take a test or go see a doctor.

Typically you ovulate around day 14 of your cycle and bleed (the onset of your period) on day 28. With this in mind, I'm not sure if I understand your question. If you haven't found an answer, please feel free to clarify your question. (I am currently working on my RN degree with a focus on women's health). I am a nurse. Not everyone is on a 28 day cycle. Some people do know when they ovulate because they have ovulation pains. If your period starts 14 days after you have these pains then you can bet you ovulated on that day. But, no you probably wouldn't experience implantation bleeding 3 days after ovulation. There is a widespread misconception that you ovulate 14 days after the start of your period. This is not TRUE! You actually ovulate 14 days before the start of your next period.

Implantation will generally take place about 5 days on average after conception. The fertilized embryo needs time to travel down the fallopian tube while dividing. On the fifth day it will become a blastocyst. Only then can it implant into the uterine wall, which occasionally causes implantation bleeding. A lot of people talk about implantation bleeding but very few seem to actually get it; it's a very unreliable sign of pregnancy.
