On Oct 10 I had sex and took the plan b. We just aren't really ready mentally for children. We had safe sex on my ovulation day (Oct 15) and again on Oct 17. This morning I woke up and there was bleeding. Enough to make the water reddish pink, stain my underwear, and I continued to wipe some up. This is the equivalent of, say, the second day of a period. I have lower abdominal cramps, but they aren't painful. I took a pregnancy test, but it was negative, of course. I am scared. Could this be implantation bleeding?

Oh, and to add, my nipples were sore the day prior and day of my ovulation. Could've been from intercourse, could have been from ovulating I suppose. But I want all my symptoms out there.

It's too early to tell. A pregnancy test won't register correct results until you have missed your next period.

What is "safe sex"? (There really is no such thing, by the way.)
