Mucous Plug? TMI Alert, labor soon? FTM.

FTM so I'm not sure what to expect here, but today I'm 39 weeks even. I had an exam yesterday. Just soft and 2 cm dilated. Not much effacement and cervix is soft and far back. I was at a 1/2 centimeter at 36 weeks. Slow progression. And my doctor expects to see me at my 40 week appointment. 😦 But I've heard from most that the mucous plug happens to be blood tinged. As far as discharge goes I've always had white watery discharge. Its been heavier the past few days but it's not my water (confirmed) . Baby dropped about a week and a half ago. Head down. Pelvic pressure, hips aching. Back aches. Lower belly aches. And occasional lightning crotch. I get plenty of Braxton Hicks but they're irregular and painless, and I went from fatigue to major nesting the past 4 days. Everything is ready for baby boy! And he's at least 7 1/2 pounds. So my question is. Is this my mucous plug? Do I call the doctor about losing it or just wait for labor contractions, which could be hours or a week away?

Update: Had some minor nausea afterwards today, a little more pelvic pressure and groin pain too. Even if it would be a week away I Only wish it would be soon! He's well over 7 pounds. Not to mention I'm crazily less swollen today as I was peeing a lot more yesterday than usual. I hope it's near I want my baby already! Lol. But I'll keep y'all posted. Thank you for the advice.
