ang_ang here again.just wanted to post more info on my situation.On the 1st day of my period i had unprotected sex and my period lasted the full 7 days but one day after it was finished,i started having light brown spotting that hasnt stopped.this has never happened to me before,usually when my period is done, its done.ive heard about implantation bleeding(when fertilized egg implants in the uterus) and was wondering if this is a possibility or if theres something else. thanx all
