Are these Braxton Hicks?

Ana • Momma of the sweetest baby boy🌟

I get period like cramps in my pelvis. I don't feel my abdomen or pelvis get tightened or anything, it is like a sting.

When I get the cramps they come every few seconds, for 3 hours or so. Then they stop. Are these Braxton Hicks or something else? They are a little bit painful.
