I have been on birth control since i was 15 i am 22 now. my last normal period was feb 11 then after i came off on the 17 i had sex on the 18 and by the 19 i started to experience common symptoms of being pregnant ie nausea vomiting morning sickness etc, so i stopped taking my birth control because i didnt want to kill the baby if i was pregnant i took plenty of preg tests including blood and urine and they were negative. i started to bleed again on feb 26 and had bad abdominal pain, i went to the hospital and they just said that it was abnormal bleeding. I still have not had a period since then, i am really really scared can anyone help. I have been to the clinic and all they have been doing is taking my blood every time i go and its really nerve wrecking
