Could I be pregnant?

Me & my hubby did it a couple weeks ago & he came inside of me. Im on BC but sometimes i take it late being that sometimes im at work when it's time. My boobs were really sensitive today& i'be been having back pains & cycle-like cramps. AF is suppose to come on the 8th, but all of this has been going on for a couple weeks. Hubby doesn't wanna test until we see if my period is late because it is never off.
