Constant cramping

Ma

This isn’t my first baby but I’ve had a lot more Braxton Hicks this time around than I did with my first. I can tell when I’m having them for the most part. For the last couple of days, and more intensely today, I have had constant period like cramping. I cramp like this somewhat during Braxton Hicks but this is different. It’s more intense and is lasting several minutes before going away. I’ve rested, drank plenty fluids and nothing makes it stop. They just eventually stop on their own. So I guess what I’m asking is do you think that the constant unexplained cramping is also Braxton Hicks or should I call my OB? I’ve also had zero energy today. I could barely keep my eyes open despite sleeping well last night.
