How different are they? Are you more likely to get pregnant on one more than the other? Side effects? I'm in need of some advice! Please comment if you'd like! Back story: had two children conceived first month. Have been trying for 5 months and decided to get check. (Everything but progesterone was normal) Blood work showed I didn't ovulate and now I have an ultrasound to rule out pcos. Regardless, I am most likely to be put on clomid to help me ovulate. I took vitex last month and I took an ovulation test and it was positive. So I know it helps but Is clomid more effective in helping me get pregnant?Any advice is welcome!
