Im 18, been on YAZ going on three months now. I was actually looking forward to a little weight gain, but haven't seen any. I got on the pill one for BC, which as far as my periods go is fine. But I also wanted to reduce the mood swings and lately it seems they haven't gotten much better. All of a sudden ill be in a great mood like I want to be, then the next ill be in a crabby mood for no reason. I also got in a car accident a few weeks ago (my fault) and have noticed that since I started the pills I haven't been as alert while driving. I always get side tracked and find myself slamming on the breaks and cutting people off, which was not the case before the pills. Does this have any relation to taking Yaz?
