Pregnant Possibility ?

So I am on the pill, I missed 3 and so I took 2 the day I realized, and then back to one from then on. 
If I remember correctly, from the day I took 2 pills I had unprotected sex 2 days later. With my SO and he came inside me. This was about a week and a half maybe more before my sugar pills. I've had the regular symptoms such as bloating. And swelled breasts. Major pms lol. But I don't feel anything more (starting cramps). Today is the day I am supposed to get my period. I feel nothing so far and I usually get it sooner then later. I will wait it out before I take a test or anything. But I am wondering if there is a chance at all? Anyone had this happen before ?
