help me

hey.

so I've been kind of anxious for the past two days.

there's this guy, he's 19 (I'll be 16 in june) and he's into me and i'm into him, so we decided to hang out on monday.

our little hang-out turned into a makeout session and then we had unprotected sex. he didn't cum at all (he let me cum though- twice) but i still feel guilty for having sex with him without any protection. no pills, no condoms, nothing.

i read a few things about precum and how it kind of works and now i'm scared i could get pregnant from his precum. i don't know if it's really possible but i'm really afraid. i'm supposed to get my period in five days and i really hope i get it. i'm going to start drinking herbal teas for women and hope for the best.

any advice?

edit: he refuses to use condoms so i said i will not sleep with him again until i get my hands on birth control. he said he's okay with that and that he's going to wait until i'm ready. i doubt he actually will, but that's okay.
