I have been on Yasmin almost a month now and havent really had many bad side effects at all. No terrible mood swings, my skin looks great, my breast are bigger...a bonus for me, but a little tender, but no so much so that they are painful, however. Im not excessivly thirsty, Im not having to go to the bathroom alot. Over all, I feel great. If I have anything new to add as I progress taking the pills I will post them.
