Sitting on a softball?

38w and I think I’ve been having Braxton hicks or prodromal labor for the last 6 or so hours. This is my second and you’d think I know what labor feels like this time around but I don’t lol

Anyways, tried to take a bath to calm things down but no luck, and now I feel like I’m sitting on a softball in between my legs. I also feel like I need to poo but I swear every crumb I’ve eaten today was immediately expelled haha

My tailbone is so sore, but I have no timetable contractions or anything. Odd. Headed to try and get some sleep now, fingers crossed!
