Labor or Just Cramping? FTM

Kaitlyn

So I’ve been having period cramps and sharp shooting pain in cervix for the past two nights. Tonight the cramps are getting slightly worse and the back pain is almost unbearable... is this contractions or normal cramping? I’m 39+3 and I’m also contracting but it’s mostly just period cramps and bad back pain. I also had diarrhea early if that means anything but no fluids. I was 3cm dilated Wednesday
