Going into labor ??

Hi mommas! I am currently 39 weeks and due in six days. Today I’ve been having to poop a lot (tmi sorry). It’s been solid but I feel awful. My head is hurting and I’ve taken Tylenol and it isn’t helping. I’ve been drinking water all day and that isn’t helping. I can also feel the baby moving around and I’m having some cramping. I’ve also had heavy discharge the past week. Does this mean I may be going into labor soon?!
