Sooo.. about a week and a half ago, my boyfriend and I had unprotected sex, however it was very short and he didn't ejaculate. My period came right on time (seven days later) but it was dark red and brown. I usually have cramps and it is heavy when it starts but this time it's light (doesn't fill up a tampon completely) and it's not red anymore (it's the third day).

I have been under A LOT of stress, so I don't know if that could affect it this much but I'm hoping that I am not pregnant, since it is brown.

If any of you could help me out I'd be GREATLY appreciated!

A brown period or discharge is normal for some girls. Its certainly normal for me. It may not even been your period. Its normal for discharge to be a brownish color as well, especially after sex.

Good luck hon. If you are extreamly worried aobut it, no harm it telling your doctor :)
