Ladies i need some input, i am 34+4 weeks and lately ive been having tightening in my stomach but its constant. It doesnt come and go like i thought BH or contractions felt like. Its also very painful. Especially when i stretch my belly, i cannot lay on my back because of it. Riding in the car is also uncomfortable. Ive been drinking plenty water and baby moves and gets the hiccups as usual. I called my doctor last night and he said its contractions but unless i had a bloody show or any kind of mucus im probably ok. Is what i am experiencing BH or contractions? I do have a lot of pressure down there. Esp when i squat or bend down. Thanks, and sorry this is long!
