Still haven’t ovulated and late period

I am on the 50 mg Clomid this round. I tested for uvulating and didn’t happen as far as I could see with testing. Doctor said my levels didn’t change with Clomid 50mg so he put dose at 100ng for next month. I still haven’t started period 5 days later. Just kind of cramping. Really praying I am pregnant but no sign yet. I’m so worried I can’t ovulate. Is this anything y’all have experience? Help plz!
