Hi, do you take yours right before bed? That's what I do, and I only have minor side effects that I wouldn't even have noticed if I didn't know they were side effects (minor hot flashes, extra moodiness). This cycle I got headaches around O time, but I think that's for reasons other than the Clomid, because I think Clomid is only supposed to cause headaches for the days you take it, not suddenly around O.
