Pain/pressure after O on Clomid?

I had a positive OPK on CD11 which was friday 8/19. Had an ultrasound that same day to check for mature follicles. He said I have 3 mature follicles.

Guessing I O'd on CD 12 or CD 13 based on the +OPK and symptoms I usually have during the time I O. But starting last night I have a ton of uncomfortable pressure in my lower abdomen. We couldnt even BD last night. Theres so much pressure I feel this weird sensation, like its pushing on my butt and vagina. Like I cant bend completly over or I am going to pop.

Anyone have similar symptoms 1 or 2 DPO when taking clomid?

I guess if this continues today I will call my doctor.
