Question for Clomid girls

For those of you who took Clomid... what were your experiences with side effects?

During the days I took it, I had NO side effects, and haven't had any of the mood swings you always hear about. But starting a few days after my last pill, I've had these hot flashes. Really uncomfortable! I also had an HCG shot on Friday to trigger ovulation, I don't know if that made things worse. Is this common?
