38wks and rectum pressure! Should I be concerned

I am 38wks and 1 days. And I've been up since 4 or 5am I felt uncomfortable and after serveral attempts to change positions it's not easy. It feels like pressure in my rectum like if I want to poop and it sorta moves to my abdomen. And I notice super light pink spotting. What is going on?? Should I go to the hospital? And two days ago I got checked and nothing still closed. And no sign of MP coming out or I haven't noticed it. What could this be help please!
