thanks Velo, but since posting this I've read that Vitex shouldn't be used if you have regular cycles. I actually bought some bc I was going to try it and then I started reading all these sites where women were talking about it messing up their regular cycles, delaying ovulation and so on, so it scared me. I probably should have done a bit more researching before posting. My doc has given me prometrium to take after ovulation until AF. I'll just stick with that for now.
