The Pill, the Amazing sex, & no condom

My boyfriend and I couldn't find a condom to use so we decided hey why don't we just forget about the condom. Well here's the thing, I had my period for about 4 days. Then it stopped. I wasn't surprised. Now, about two or four days later, we had sex without the condom. I'm on the pill but lately I've been busy that I would forget to take it during the past week. Well, my boyfriend finished the first time while I was on top of him. He did pull out. He then wiped off the cum and entered again. The second time he was on top and it was all over me. He pulled out also this time. Do you think it would be possible to get pregnant?
