Thank you both. i do plan to call the doc soon to see whats goin on.
I'm experiencing the same thing. It usually happens after I've been standing or walking for a period of time. Pressure all on my stomach, except mine is hard when I feel it. I wasn't sure if it was Braxton Hicks or if it was just baby pushing against my uterus. Seems BH are the general consensus. I plan to ask my Dr about it at my next apt just to be sure.
Sounds like braxton hicks to me, the body's practice run for labour. But, if you are unsure, call a dr.
