help!

So my SO and I went away for the weekend before Valentine's Day and had sex many many times! The Saturday night we had sex, and he stayed inside me for longer than usual, as I moved off of him, we realised the condom was no longer on him, it was stuck inside me.  Now I don't want to seem stupid or anything but is there a chance I could be pregnant?! I know the semen would've stayed in the condom or come out as I moved from my SO.
