35w tmi!

So the past 2 days I’ve been feeling the urge to use #2 but when I try nothing comes out. I eat lots of fiber and drink so much water btw. Anyways my stomach gets crampy along with my back and I try to go but I just can’t before this I had lose stools now it’s hard to go am I just constipaded or? My friend said this is how her labor started but I’m only 35w have a dr appointment Wednesday..
