Lately when I walk or sit, my uterus is soooooooo tight and its crampy somewhat. like period somewhat cramps...

I am guessing this is normal?

not really.... braxton hicks aren't supposed to be crampy (like a period) -- those sound like regular contractions.

if youre dehydrated, you can get contractions like that

I just drank an ass ton of water.

Its weird, since you know I have those hip boney issues, it really feels like that when my hips are sore.

I usually take a tylneol before bed.

I am going to super hydrate myself today to see if they go away.

slight cramping can be normal. Are they in intervals tho? Try laying on your left side, make sure you empty your bladder alot and drink tons of water. If they seem like they are in intervals then call. It could be contrax. But cramping can be normnal as the baby is moving, balling up and the like

My uterus has started getting super tight anytime I roll onto my back...lol. Doesnt usually hurt though

For sure ask your dr when you see him again
