Thread: Brown discharge for over two weeks?

I'm 15 (almost 16) years old and...well, I don't know what's going on, so any help you can give me is much appreciated.

I had a period on September 5 (of this year). My boyfriend and I were fooling around on September 13. He was teasing me, but his boxers were on, and he constantly moved them around so the wet spots from his pre-cum wouldn't touch me. Scared of being pregnant, I took Plan B within 24 hours of it happening (on September 14). On September 19, another "period" came thanks to the pill.

We had sex for the first time on October 2 at around midnight; it was the first time either of us have ever had sex, and we did use a condom. We did it again in the same night, and we've done it 10 other times on different days (all with condoms). When I woke up on October 3, I had slight abdominal pain and pink spotting/discharge. Since then, it's gone from pink to brown, and it hasn't stopped.

It isn't my period, I know that for a fact because it's usually a moderate amount of red blood. There isn't enough brownish discharge for me to have to worry about wearing a pad. I also don't think it is implantation bleeding because it would have started almost a week after having sex; this was within a few hours of it and it's been going on for a while.

I've been doing research on this for days, and so far all I've heard is to visit a gynecologist. I'm not sure if I should make an appointment yet, though. I was going to wait and take a home pregnancy test (possibly two or three) because even though we have always used condoms, having a baby is still a possibility. We also checked the condoms after we finished; they were never broken and didn't have any holes in them.

I don't think it is an STD because we lost our virginities to each other. Could it just be that he was too rough on me, and it was my first time? Is it an infection? Do the type of condoms we used have anything to do with it (Trojan with spermicide)? And could the hormones from Plan B be the reason why I haven't had my period?

I'm trying not to stress out about this, but I know it's important that I find out what is going on. And I realize that I'm not going to know for sure until I go to the doctor, but it's comforting to know that other people have or are going through something similar. I don't want to hear that I'm too young to be having sex, because I knew about the consequences even before it happened. I chose to do it.
