I think my bf gave me an sti

I’m freaking out.

This morning I woke up with a pain on my vag. I assumed my underwear had pinched me during the night because that’s kinda what it felt like.

Well I went all day and I just took a look at it and it looks like a rash or something. Almost like blisters and it’s painful. Very not comfortable.

Tomorrow I’m making a appointment but if he gave me something imma be so mad. I know I was clean as I got tested. I trusted him.

Im trying hard not to jump to conclusion but ugh. Just worried.
