I don't know if I'm pregnant or not. I'm a college student and am 20 years old. Almost 21. I have not started my period yet and I'm very worried. I don't know what will happen should I be pregnant. My boyfriend is amazing so I have no question if he'll support me or not. I know he will! But this will change everything! We were so careful, I'm still not sure how this is even possible. I'm on birthcontrol and we used condoms every time. Yet, I've been on birthcontrol since I was seventeen and NEVER been late. I always knew the day I would get my period and it always started.
