I've been on Avaine for 2 months now... And I'm feeling so crappy right now. I've always had an irregular period, where I would miss a month or two then it would come back with a vengeance and last for almost a month in a half. I never had cramping until I started taking this pill. Last month it was so unbearable I was in the fetal position at my aunts house. She tried desperately to comfort me but nothing helped. I ended up going to the emergency room. I was given morphine and some other pain meds. The doctors thought it was my appendix at first so I was given an ultrasound and a cat scan. My ovaries were fine and everything was fine. Six hours in the emergency room and I was told it was really bad menstrual pain. How lame is that? Anywho I went to Australia with my bf and well yea you know... Now I think I'm pregnant... so thanx Avaine. Not sure what to do anymore, afraid if I stop I will most definitely become pregnant. I'm going to take a test.. not ready to be a mom. Cross your fingers for mr guys!
