So I stopped taking birth control pills in march 2011 because they were making me sick. I got my period ever 32-37 days until sept. That was 45 days I took a test it was negative. I didn't get it again till nov. Which was 56 days. Took another test still negative. I haven't had my period since nov and its been 77 days. Since the summer I've gained 25 pounds and most of that was in the last 3 months. I went up a cup size. And I've taken 2 more test. Still negative. I'm wondering if I could be pregnant. Even though the test keep saying no.

Birth control regulates your period. Since you've stopped taking them, your body may have trouble ovulating, therefore menstruating, regularly. The shift of hormones could also result in the weight gain you described but we can't give you a proper diagnosis over the Internet. I suggest calling the doctor who prescribed the birth control for you and make an appointment to discuss what's happening.

I would go to the doctor and find out what is going on.
