i am a 19 year old female that has always had extremely irregular periods. but they always last 7-9 days and are usually pretty heavy. 2 weeks ago i bled for 2 days VERY lightly, and yesterday i started bleeding lightly again. my breasts have been extremely sore for about a week, but i have no morning sickness. it is not easy or might even be impossible for me to get pregnant. i have unprotected sex with my boyfriend a few times a day and have never gotten pregnant. i know its not him being sterill because with my last couple of boyfriends, i didnt get pregnant either. i dont have medical insurance so i cannot go to the doctor. PLEASE SOMEONE HELP?!?!
