Hi, i took plan b a few months ago in the middle of june after having unprotected sex while on my period. A week after taking it, i started my period again so i started taking my birth control again and after finishing the pill pack i bled for 2 days and haven't had a period since. I also stopped taking the birth control because it made my period somewhat clotty. I was on Gianvi. Its been a few months and I still haven't had a period. I don't have any pregnancy symptoms other than a gassy, uncomfortable feeling in my right lower abdomen. I have no weight gain, breast tenderness, mood swings, etc. But I just started college and it's very stressful. So i don't know if thats the cause...
