well i had unprotected sex on 4/5 it was one of those night and i don't really remember it...but i was supposed to have my period the week of 4/15-4/19...however after having sex i had brown discharge for the following week which i thought was maybe my period starting early because a few weeks before i had missed a few days of pills...after reading my pill pack it said to throw out the old pack and start a new one the week that your period would come and it was possible that your period wouldn't come that month...but the discharge hasn't stopped and i'm going on my 3rd week since having sex and i don't have any other pregnancy symptoms and the test i took on 4/20 was negative..do you think my discharge could just be the period i was going to have but stopped it because of taking my new pack of pills? please help..
