Contractions?

Jennifer

I had my second membrane sweep today and was told I’m at 2 in a half cm.. Since my doctor appointment I’ve had cramping and definitely some kind of contractions.. I’m just not sure if it’s real ones or Braxton hicks 😕 when it happens I get kinda strong cramping in my lower stomach and lots of pressure in my lower back.. I definitely have to stop what I’m doing and it’s hard to even talk. It only lasts about 30 seconds. Are these real? Should I go to the hospital… btw I’m 39 weeks 4 days.
