Ovulation during taking Clomid pill?

I took clomid this cycle. I was supposed to ovulate today, but I never got a positive ovulation test. I have been testing morning and night every day for ovulation. I am sick to my stomach and fatigued. I feel like I did before I misscarried a few months ago. Is it possible that I ovulated while I was taking the Clomid pills and I got pregnant? When I got pregnant a few months ago I started having morning sickness just a few days after I got pregnant.
