Ease my mind.

Okay, I'm 19 but have been raised with a mother whose very anti sex. I'm super inexperienced which is pretty embarrassing at my age. (I literally just started masturbating this year?) but I hooked up with this guy, sorta oral sex ish but mostly mural masturbation. (He had clothes on. My underwear and pants were down) According to Glow I had an 8% of pregnancy that day & now I've been nauseous and feeling weird and I'm super nervous. I read around and many of you say everything's fine but I just want to hear some advice and comfort I feel super dumb and it's so embarrassing
