Early labor?? Please respond!

Sorry if this is tmi but I heard diarrhea is a sign of early labor if accompanied by Braxton hicks (or may be the real deal not sure- ftm) and cramping and back pain which I've been having as well... It's been on and off for 24-48 hours now. EVERYTIME it happens I make sure to hydrate and lay down and it eases but the Braxton hicks are becoming a little more frequent... Almost about 8 in an hour. I'm 36 weeks with my first. Should I ring my midwives just to be safe or am I overreacting? Baby is moving around fine and I drink a bottle of water Every time I have the diarrhea. I'm nervous baby girl is trying to make an early entrance! 😬
