Worst Diarrhea

Am at 39+1 today, suddenly while working had the urge to poop. Went to the toilet and was suffering from getting the poop out. I thought I was in labour. But not sure what contraction feels like to start off with. My tummy was in pain and I was sweating like crazy. Had cramps while trying to push the poop out. But didn’t manage to actually shit. Is this signs of being in labour? The urge to poop Is real but nothing wants to come out. Diarrhoea whole other level. It was draining my energy. Am I suppose to go to the hospital just in case I’m actually in labour? But no water bag or mucus plug seen. #firsttimemom #pleasehelp
