Does Braxton Hicks feel like period cramps?

Rica

I’m confused. I looked it up and said it feels like a tightening in the uterus that shouldn’t be painful. I’ve been having some cramps here and there that don’t last long at all and are very irregular but it is a but painful, like mild period cramps. My sister who’s had a few babies keeps telling me it’s Braxton Hicks but google tells me they shouldn’t be painful lol so I’m not sure what to think!!
