31+3 what should I do‼️

hailee • Momma to 2 beautiful baby girls && baby girl number 3 on the way ✨💗

I’m 31+3 pregnant with my second, the past few days I have had a increase in discharge, cramping off and on, steady back pain, and ALOT of pressure down there especially when I sit down to use the restroom. && Tmi I’ve been having like diarrhea kind of poop. But baby is still moving. I’m just wondering if this is common this far into pregnancy or if I should go in to the ER or something?
