I had mood swings...much like pregnancy. Clomid increases progesterone, so it is not uncommon to have pregnancy like symptoms. Mood swings can definately be one of them. Good luck.
Clomid did nothing for me, as far as having my hormones crazy. I was expecting the worse, since I had read all sorts of crazy side effects, but I was totally fine. I didn't feel moody, it was very non eventful, or even get a headache. I was on the CCCT 100mg.
Best of luck;
