Hi. my name is Kaila, i am 16 years old and i am sexually active with my boyfriend of two years. I have been on birth control (orthro tri Cyclin) for about a year and six months. My question is, does anyone know why i have what seems like two periods a month. I will explain: I started my period on March 7th, and March 18th i finally quit. Yes everyday was heavy bleeding, then March 19th though 21st i was clean with no blood, March 22nd came and i started heavily bleeding once again until March 27th. It was horrible, the worst part is this happened to me in Oct. Dec. Jan. Feb. and March, my period was 5 early this month and i have seen no bleeding since April the 15th, today, the 24th i have been spotting really bad to where i have to wear a tampon or pad. I do not understand why this is and i have went to see my gynecologist; she told me that she did not know what the cause could be, i have no STD nor AIDS nor the AIDS virus, i have been tested for all and i do not have a cyst on my ovaries either. At only 16, i have had a rough time. Please if anyone knows why will you answer!
