Hi, I'm 19 and I've been on birth control for 2 years and have been sexually active with my current boyfriend for about a year. My normal period happens every four weeks, starting on Tuesday and ends about Sunday. My period is coming up,but today is Monday, so I'm not really worried yet, but today and this past Friday I have been having stomach pains, little cramps, and dark brownish discharge, that doesn't have a strong smell, but with a faint sent of blood in it.
I don't know what this means, I sometimes have the dark blood at the end of my period, but never at random times like this... if I don't start by tomorrow I guess I'll have to see a doctor.

Has anyone else had this?
Plleaaase don't tell me I'm pregnant...

Cervix could be bruised from rougher than usual sex, or you could have and std, or you could be pregnant. The only way to know for sure is to check with your doctor.
