I had a cramp in the car on my way home from the store and it was pretty intense like a period cramp not unbearable. It went from my stomach to my back back to my stomach. I timed it to see if I had another one and I did 12 minutes later and another one 10 minutes later. I stood up on this last one and tried to move and it just stayed in my back. I didn’t see how long it was but it is a little concerning. I’m 27 weeks tomorrow any help would be appreciated. I’ve never felt a contraction or Braxton Hicks before.
