Am I crazy?

I had a d&c back a couple of months at 16 weeks  due to a missed miscarriage. My body is back to normal, AF came 5 weeks later. The month of June, we had sex during ovulation peaks and swore I was preggo due to symptoms I related with last time. 
I got my period tho only 2 days late but no cramps not much clotting in blood. Is it possible I could be preggo? 
Am I delirious? Too scared to take a test to face reality.
