I am really worried and in need of help! Im going to give you the full story to help you better understand my problem. Me and my boyfriend of a year has sex occasionally. I never had any problems when it came to my vagina or anything, miss periods, and ect...June 10th, my period came on and lasted until the 13th/14th. Later that week we had sex and on the 19th I took the Plan B pill, which brings on your period again. I received my period June 24th/25th and it lasted until the 28th. The 29th we had sex and after that, when i urinate, i would see dark red/brown only when i wipe. And i thought this was from my period because that usually last for a day or so. But this time, it happened everyday when i wipe myself and starting yesterday, it started flowing and today when i checked, i needed tissue or a pad. I ve been told to see a doc but it could mean a miscarriage, old blood, pregnancy...or worse, and STD. I need to know what this could be! Please help me. I never experienced this before. Only 1 sex partner since 2yrs ago. My email is YYYY@YYYY
