38 weeks and freaked out

Guys, Ive been having super intense contractions but they are like 45 minutes or just all over the place, I was 4 cm dilated last week when I got checked, and I have an appointment today at 10 am. Me and my bf had sex a couple hours ago and now my vagina feels so weird, it feels like it’s bulging . I went to go pee and noticed how weird it felt so I did a little exploring and now I’m freaked out, I can’t even go to sleep. I don’t want to go to the hospital because I’m not contracting like that. Anybody else feel like this?
