Lower belly cramping pain? Contractions?

Fabi
Ok so I woke up today with a pain that comes and goes I get cramping in my lower belly it goes away and a couple of times has stopped me from moving. Also been feeling as if I have to take the biggest poop! Sorry a little tmi but ugh what is it are they just Braxton hicks? Or real contractions? Does this mean labor is near? Btw my due date is tomorrow.
