Braxton hicks - what do they feel like?

Mrs.S • Wife, mother, writer... ❤️ a good debate 🗣 Living in the Land of the Free 🇺🇸
Seriously, this app and lots of other ones make it sound like having Braxton hicks contractions are totally normal once you reach 20 or so weeks. I'm 23 weeks and today during my routine OB appointment my doc told me to get ahold of her if I had so many BH's in a two hour period. She tried to explain to me what they feel like but I'm still confused. So I'd like to ask you ladies.  Thanks!
