Braxton hicks

Joann • 32 yrs old mommy of 2 healthy boys and another boy on the way. Proudly married to a soldier for 9years.
I'm 23weeks and woke up with severe cramping at 5am at first I thought it was food poisoning and that I just needed to use the restroom but that wasn't it. It lasted an hour with cramps lasting a minute or two each time. I finally went to sleep and I'm fine now. Has anyone experienced this?
