Unprotected sex

I had unprotected sex last week. It's been 10 days since I had it. My boyfriend never came in me and he pulled out way way before he was about to come. I never took the morning after pill or anything and I'm not on any birth control pill. We usually use condoms but this was a one off - in the moment kind of thing. My breasts have been feeling swollen and I feel really bloated. I have back pain and my period is due in 11 days. I don't know if I should wait and see if I get my period or if I should get a pregnancy test? Does anyone think I might b pregnant even tho he pulled out???
