menstrual disorders
"I just started my second pack of microgestin fe 1/20 and I cannot complain! I definitely have the side effect of feeling a little sick, but that is to be expected. My first month of using it I also had started working out and I actually lost 7 or 8 pounds, so I had no problem with my weight. I'm sure it is based upon your body, but if you maintain a healthy lifestyle weight gain should not be a problem. 

I started taking this due to the unreal pain I was experiencing while I was on my period. This past one was nothing! I had zero pain and it was extremely light and only lasted about 2 days. It was so nice! My only complaint is my stomach hurting during the first few days of pills."
