First time w/o condom

So I just recently started having sex, and still learning things, my bf is very patient with me and is very sweet and gentle...I found the best man. The first time we had sex he couldn’t exactly get the condom on so we decided against using one, plus I took my pill right before we did the deed...I had no idea my first time could be so painful 😓 so I didn’t let him stay in long...anyway, is there a chance I could still get pregnant?
