Confused?

Kait

So I just had sex with my boyfriend in a new position yesterday, where I’m laying on my stomach and he’s going from behind. (Best sex I’ve ever had btw) Somehow he got deeper than normal, and now I’m in pain? It’s like when I sit down, and it’s upper vagina/cervix pains. Am I gonna be alright? Ya girl is worried. Also ya girl is 3 days late on her period, but I took a pregnancy test the day before yesterday.
