AF After MC at 5 Weeks? May Be TMI.

Marissa
I was 5 weeks pregnant when I miscarried 29 days ago. According to Glow, I should have gotten my first period on Sunday. It is now Tuesday, and still no AF
My husband and I began making love again two weeks after the miscarriage, as instructed by the doctor, but we weren't supposed to start TTC again until my AF came. Unfortunately, I wrapped my legs around my man our first time making love again, and he was unable to pull out in time. 
Is it possible I am pregnant again, or did I just not AF because of my MC? Excited but nervous simultaneously. Any personal experience with this?
