I have endometriosis. I typically have very frequent, very painful periods (multiple periods per month). However, I've been stressed the past few months and have no period, since March 14. But, I have had pain. I have been trying to get pregnant for the past several months with no luck. I constantly take home pregnancy tests, thinking something might have slipped up on the previous one, only to find out that, it too, is negative. I read about chasteberry a couple days ago, and picked some up at the vitamin shoppe. I am hoping this will start my period, because my OB-GYN gave me some fertility drugs to take once I have started my period. However, now I wonder if I should take chasteberry right before I take Clomid...and if i can take chasteberry, how long do you think it will take to start my period? Ive only been taking chasteberry for two days, so if there are any nasty side effects i should know about, please let me know.
