Braxton Hicks? Early labor?

During sex I got a sharp pain and had to stop. Since then I have been getting bad pain/pressure on and off. I started timing it and it's pretty consistently every 8-11 minutes and around 30-50 second "contractions" I guess?! I don't know I've never had contractions.

I'm only 26 weeks so I really hope I didn't onset early labor or something. 😭
