Early labor??? FTM

Allyssa

A few days away from 37 weeks

I’ve been feeling what I can only describe as a mix of period-like cramping and constipation pain in my lower abdomen, lower back and upper thighs for the past few days and I’m not quite sure if this could be a sign of early labor?

I have a very hard time knowing if my stomach is tightening at all since it’s consistently rock hard.
