Diarrhoea, 37 weeks, early labour sign?

Natasha✨

Been experiencing diarrhoea for a few days but other than feeling totally exhausted I've been feeling completely fine, is this an early labour sign? Curious as I have been constipated the whole way through so is strange to be having this now, also been having On and off cramping throughout these few days although hasn't been regular just stronger than braxton hicks
