hi, im a 15 year old african american girl. i am also 100 pounds over weight. I was curious to know can i be pregnant. i havent had sex in 7 months and i have had my period everymonth, even twice a month. i have had slight bleeding but nothing heavy it has just been cramps and blood clots. i get these movements in my stomach and i can sometimes see it. its almost like popcorn and other days its like a wave or something. my breast have been really sore, but im birth control. i recently took a home pregnancy test and it came back negative. i dont want to go to the doctor because they might look at me like im crazy :/. i have never been pregnant before alothough i think i had a miscarrage at a younger age. i was having the heavy bleeding, leaking breast and so on. i just need to know your medical oppinion and anything else that might help.
