Hi I lost my virginity 3 weeks ago. I'm on birth control (Cerezette) which usually stops my periods. However the week after I had sex I had a week of heavy bleeding and pains (it felt like a regular period) but now I have slight abdominal pains. We used an extra safe condom and it never broke- however because it's my first time I'm just so so paranoid that I'm pregnant. Helppp
