birth control
"I have been on Yaz for a couple months. I decided to switch to Yaz to gain weight and clear up my mild acne. Overall I have had a positive experience with it. In the beginning, my periods lasted only a couple days, but now, I have no period at all. Also, my face is clear, but I did not gain weight from the pill. The weight I have gained was from muscle weight from working out. I'd say the only negative were my massive headaches when I did have my period. The headaches would come on my first day of my period. But now, with no period, I have no headache!"
