I am 19 and 5 days late…am I pregnant?

My last period was dec 14-18 and I had sex (condom, and pull-out method were used) at least 3 times since. We had sex while I was ovulating according to the Flo app). He is super careful with the condoms and often puts new ones on if he has to pee ect.

Since we are both so careful I seriously doubt I am. Yet there’s this nagging feeling I have. I have been having tiny cramps all day today, every time I check to see if it’s my period it’s not. I also have been having cravings, and my boobs are large and tender. This could all just be pms symptoms.

I also have never been super regular.
