Doubt!

Due to amenorrhea, I was being treated with Provera to get my periods, but I wasn’t ovulating. Last, month I tried my 1st opk and ovulated by my own onCD19; I finallly got period naturally (without Provera) this last Wed.13, today is my CD3, and I was told by my doctor to start taking Clomid today. But now my doubt is if Should I take it OR just wait too see if my body ovulate again on my own (maybe around CD19)??? (ps: I couldn’t contact him today)

Thanks!
