Early labor?

BrittanyLee❤️MommyToBe
My SO just got home from a week long vacation to visit some family and I didn't go, do to work.. Well he got home yesterday and we really missed each other.. (TMI, we've been humping like rabbits!) Lol but I've noticed that my tummy has started to cramp up? Could to much sex start an early labor? I know it's used to induce labor when the time is right but I'm 22 wks and 3 days. Definitely don't need little man coming out anytime soon. Should we chill out alittle, or are we okay?
