Help! Am I pregnant?

Ok so I'm suppose to be on my period next week I know this for sure because I take the birth control pill, however I have missed 3 days of the pill this month not in a row but yeah. And the past like 2 weeks I have been having unprotected sex and the guy I was with has cum in me like 5 times I was to say over the time. And I have been getting cramps a little and I feel bloated and my boobs are a little sowellen. I'm not sure if these are normal period symptoms or if they are a sign I could be pregnant. I'm not sure the last time I ovulated I know my period was around June 15 last month. But I'm really scared could I be? Or not?
