im 18 years old and i lost my virginity exactly 5 weeks ago in march. my period has always been iregular (skipping months at a time). i had a period in jan but i spotted about 2-3 weeks before AF. which never happend before (couldnt have been pregnant then -never had sex at that point). after my period stopped i had sex about 4 weeks later using the pullout method (not the best i know) a day or 2 after i started spotting red and pink real light i thought it was my period but it stopped. less than a week later it started again, ive been spotting for 4 weeks sense then, always red or pink with clots here and there (tmi sorry). there were times i thought i was starting a period but always back to spotting. i thought it seemed to get heavier the more i exercise but it hasnt been consistant. i stopped a few days ago but im starting again, im really stressed and scared, im tired of spotting every day. i took a pregnancy test 2 weeks after sex, and 25 days after sex both negative. i dont have any other symptoms of pregnancy other than the spotting. occasionally i have mild cramping but its barely noticable. my breasts arent sore im not overly tired, or urinating more often. could i be pregnant, what could be wrong with me if im not pregnant, why am i spotting like this. please share advice and stories, i need advice. thanks guys
