PREGNANCY SCARED NEED NELP PLZ TEEN!!

Ok so I'm 16, and I just had unprotected sex it is 1/3/19 and its like his 4th time having sex and using the pullout method HIS SWEARS HE PULLED OUT AND THAT HE KNOWS WHAT HES DOING but this is my first time I'm was a virgin and my fertile window ended two days before we had sex but I'm still scared that I might get pregnant I JUST NEED HELP (I also did a baby wipe clean)

Update(he won't buy me a plan b, he swear that he didn't cum in me and that I'm not pregnant, I have very strict parents and I have no ride to go get me a plan b so he suggested on drinking to a miscarriage I don't want to but if I am pregnant that's my only choice)

Update I’m not pregnant I got my period thank y’all tho❤️
