Am i pregnant?

my boyfriend rubbed his penis in my vagina from behind so his tip was on my lips or clit, he didnt cum but i think he precum but i couldnt tell since i was also wet. he wasnt close to my opening and he didnt put it inside. i searched it up, precum can contain sperm if he recently ejaculated but his last orgasm was 2-4 days ago and some remaining sperm can be washed away when peeing. but he was a bit close, not super close but still close to cumming and thats when he took it off of me. can i still get pregnant?
