pcos clomid and ovidrel

Dalylia
I have pics and after a long few weeks of bad days and stress I finally got the okay to take my ovidrel shot last night and had sex at 2am now I'm having sever cramping!! Maybe it could be ovulation? I started out with five follicles all measuring about 10mm after 100mg of clomid but then I was put on 150mg the week after so yesterday when I went for a ultrasound I only had two left one was a 18mm and the other was 22mm. Anyone else been through somewhat the same and had success this is my third cycle with clomid and ovidrel.
