amenorrhea
"My first birth control experience was a disaster; I was taking Tri-Sprintec. Tri-Sprintec made me gain 20 pounds, acne, increased my periods, and did the exact opposite of what it was supposed to do. After one year of searching the internet for an alternative option I came across the Depo-Provera shot. I have been on it now for 9 months (so this is my third shot), and I have come across no weight gain/no periods, and I think I am one of the few women who has been so lucky. The only thing is, for the first month of EACH shot you have bloating, some pain, a little headaches, etc. It goes away for me after that. Nothing I can't handle compared to the periods I was getting before. Everyone is different though but I highly recommend this!"
