question: Okay so im on birth control, ive already had my period , it was on dec 12th me and my boyfriend have unprotected sex all the time , i know i shouldnt but we do, this morning i woke up and brown liquid dripped down me it was only a few drops then it stoped, then later on it started again so i put a tampon on , then cramping started , is this my period again? its extreamly light like barely even there but i dont want it getting in my underwear. or is this an early sign of pregnecy?
