Moms of multiple kids please respond!

Currently cooking baby #4 and this is THE only pregnancy where I experience Braxton Hicks(or notice them for that matter). I’m almost 21wks. The only other pregnancy I had them was my last in 2015, and it was passed 35wks and maybe once or twice. This time they started about a week or two ago and now it’s like every time I try to do house work I get them! They don’t HURT they’re just uncomfortable and odd like an abdominal cramp not even a uterine cramp! Moms of multiple children, with each pregnancy did Braxton Hicks get worse? (I am hydrated and WELL rested, my 3yo lets me take a nice nap during the day while my older two are at school so I can’t find a reason for all of a sudden getting them for the first time in my mommy career other than just having had a lot of kids lol 😂). Thanks for the replies!
