not on birth control, had unprotected sex!

So I'm not on BC yet (literally my appointment is this week oops) and I just had unprotected sex Friday in which he never actually fully came inside of me but we went several times, with a blowjob in between. Then on Saturday we did it again but only went for one round and finished w anal (sorry if this is tmi it's important). What's the likelihood that I'm pregnant. I'm supposed to get my period any day so I'll know soon but I'm still freaked out.
