Start of bloody show?

I don’t have a picture because it came out in the tub, but I’ve been losing more and more of my mucus plug - I know it grows back - However, now it’s tinged with light pink and brown blood. The night before I had strong menstrual cramping from 10pm-6am, contractions every 25 minutes for a few hours that stopped on their own, back pain, nausea and vomiting, and pelvic pressure. I was in and out of the tub 3x all night, which didn’t help at all, and went in to see my OB at a scheduled appt the next afternoon where she said just false labor which I figured. I’m only asking if this sounds like the beginning of my bloody show because I didn’t experience this with my first two kiddos since I was induced due to high blood pressure.

If so, how long after - if you’ve experienced this - did any of you mommas go into labor? I’m 36+4. Thank you in advance!🖤
