first cycle with clomid

First cycle with clomid. Af should be due by May 16. I was in clomid 50mg cycle days 3-7.. HSG was fine, no tubal blockage. Ultrasound showed three follicles on my right side. 10000 of pregnyl yesterday so I'm hoping I ovulate. I was diagnosed with PCOS so I can't do opk. My question is do a lot of you ladies get fertile cm on clomid? And did your doc give you a trigger shot or just the clomid?
