It didn't hurt or anything just made feel like I had to pee and I did it wasn't very much but I peed lol

Yea those are braxton hicks. mine was very uncomfortable. I couldn't walk for a few seconds

Ahh. Idk if it was that or baby moving but it felt like tightening up and loosening it didn't last long

when I got it for the first time, my stomach just got super hard like a big cramp.
