I've been taking Yasmin for about 2 months and my moods are out of control. At first I thought it was stress and tiredness, being a mum and moving house, but now we're settled in our house and I still feel crazy! I know it's hormonal because there's still a rational voice in my head saying "Why are you over-reacting so much?" But I can't control the negative thoughts or angry comments that fly out of my mouth. Also, I've basically had 2 weeks out of 2 months that I haven't been bleeding, and not just spotting but proper periods with associated pains. I've craved chocolate like never before and I'm hungry all the time. I hate feeling so crazy!
