First round of Clomid

Hi everyone I’ve been TTC for 8 months, I’m supper irregular and take medroxyprogestorone for AF, I’ve done ultra sounds, HSG test and everything came out fine and good but according to my blood work I am not ovulating so my Dr just prescribed me Clomid. I took my last pill yesterday, I’ve been tracking with opk but no ovulation yet. Do you guys know how many days after should I expect to ovulate and if any of you have been successful ovulating with Clomid?
