hello, i have a few questions to try and understand my situation better. i was supposed to start my period 2 weeks ago but i didn't get it . Last Saturday i had sex unprotected sex, he pulled out but i started cramping a little bit the next day, not my usual cramping because i get very bad cramps and these were super light. i didnt think of it the couple of days until Friday evening i got my "period" but it wasnt my typical reddish color it was like a brown discharge and today it was gone. i dont have my period anymore. what could this mean?
