I've never told anyone this. Until now. When I was 17, barely graduated from high school, I had my period. I'd always had very bad cramps and a heavy flow because of a hormonal imbalance so when it came I didn't think anything of it. I was just glad it came after having had unprotected drunken, unprotected intercourse with my boyfriend of 2 years. On the second day, while I was going to the bathroom, I looked down at my pad to see if the flow was heavier than normal. What I find was clotted blood with a little yellowish pink ball-like thing in it. It was a little smaller than a pea and it looked like a bunch of little balls fused together. It was hard. I was scared so I never told my mom. Can anyone tell what it was?
