Missed two pills...possibility of getting pregnant?

So I have been on the pill for a while and I forgot to take it the last two days. Normally I would be ovulating at this time but I know birth control stops that from happening. So my boyfriend and I had sex on the third day and he ejaculated in me. How much of a possibility is it that pregnancy could occur? I have a dermoid on my last remaining ovary if that makes a difference. P.s. I'm not worried of getting pregnant. We would love to have a baby together.
