I am soooo confused.

Okay FTM here. 2 days over due, and not sure what to look for . I've never my whole pregnancy had Braxton hicks or any thing so I'm not sure what contractions are like. Now, since 6am, about every 5-10 minutes I get the worst feeling that starts in my back, and wraps around my front, and feels like a tightening feeling in my lower belly/pelvic area. I also feel a lot of pressure everytime it happens. Throughout the past 4 hours they've gotten worse, but it's still bearable. Is it contractions ? If so when should I head to the hospital ? Also, (TMI) how much mucus plug is there ? I've been losing mine in giant yellow slimy clumps since Wednesday, plus a bit last week and the week before, but now it's constant, like everytime I pee there's more. Nobody explains this stuff so I'm pretty confused 😒
