could i be pregnant

i know i know i might get made fun of this. so i’m on birth controls and have been on it for about a month now and take it almost perfectly. i always have sex with a condom just to be safe but me and my boyfriend had unprotected sex last night. i’m pretty sure he didn’t cum inside of me but we went two round and he didn’t pee after the first so there was sperm in his precum. the second round i was on top and as soon as he pulled out he was cumming. i don’t know if he finished inside me he said he didn’t but i took a plan b just to be safe but i think i’m just having anxiety about it. am i good?
