Question: Implantation Bleeding

 sam_shepherd - Thu Nov 19, 2009 3:50 am

I have read a great deal of conflicting information about the vaginal bleeding associated with the implantation of a fertilized egg after conception. A friend of mine is very concerned after five days of bleeding which is more significant than spotting, but not quite as heavy as the peek days of a period, nor is the fluid the same consistency as a period. This bleeding started the day after a sexual encounter and I've read that implantation bleeding begins a few days after conception. She has just recently started taking birth control again after several years off it. She has not yet finished her first month on it in this new cycle of pills, so they would not be effective yet. She is a smoker, which I have read can contribute to similar bleeding while one is taking birth control pills. When she was on birth control in the past, she did not experience breakthrough bleeding and was a smoker at the time as well. She intends to take a pregnancy test, but must wait a while longer for accurate results. I suppose my question is this: how likely is it that implantation bleeding would occur the day after conception, and does this sound like breakthrough bleeding, or pregnancy? Thank you for your time.

User avatar Hello,
It sounds more like breakthrough bleeding to me. You are correct that implantation bleeding would not occur that soon.

An unusual period or two is quite normal and hormonal birth control definitely have an effect on these. Taking a pregnancy test is always fine for reassurance but oral contraceptives are very effective as birth control and the odds are not great for pregnancy if she takes the pills as directed without missing days.

Best wishes.
