I started Yaz about a month ago. The first two weeks were horrible. Crazy mood swings, tired, head aches, my face broke out so bad, extremely bloated, I was very close to giving up on it. The next two weeks my face cleared my mood was happy again, still a little bloated less tired. I am now on the first day of my sugar pill no period yet. I usually get it on Sunday or Monday. Less cramps however very nauseous and having to go to the bathroom with a upset belly. So far no weight gain but doubled in boob size
