Could I be pregnant?

I've had sex with my boyfriend only 2 times in this month: with a condom for both times & he also didn't ejaculate for both too. (We just decided to stop mid way) & the last sexual activity we had was just making out and humping each other. We both got wet but we were in our undies, really don't think any of his sperm can be inside of me from that. 
I didn't have much discharge recently. Experienced the normal mood swings/pms a week before I supposed to start my period & had my period cravings like usual too. 
But my period is 2 days late. I'm barely late for my period every month. I know my period is not that late yet, but I'm starting to get worried. Does anyone have an opinion on this? Would appreciate it xx
