What are the chances of me getting pregnant?

This is probably going to sound stupid but; Boyfriend and I had protected sex last night. He came in the condom, took it off and licked the excess off (so just a little was on my tongue probably). After he left, played with myself using a dildo and sucked on it in between playing forgetting I had licked the excess cum off earlier. It's highly unlikely that I could get pregnant from this, right? That's what I think and my gut tells me but I'd like reaffirmation.
