Feeling off the last few days

The last few days I have felt off , baby isn’t moving much , he moves but not like a lot , I’m 36 weeks pregnant, i have been crampy and loose stools . Not sure if baby is telling me he is getting ready or what . I have also had really bad Braxton hicks the last couple days. I’m not due until August 22nd. Has anyone had this and it was a sign baby being born was near .
