Is this it? Possible labor??

So the last week I been having painful contractions off and on. And yesterday I was only 1cm dilated and 60-70% effaced. Still been cramping off and on but I ignored it since I figured it was nothing. Anyway I did my normal thing woke up at 5am before my son got up got a shower, did some pregnancy yoga then I did labor inducing meditation (didn’t think it would work???) but other wards was super relaxing. I then proceeded the day so far got some food then took my son to my moms to visit awhile. Well before I got out of the car I thought I peed some then when I got into the house it did it again! Ignored it, and put my son into his crib to take a nap as I’m so tired right now. But anyway went to pee, and when I whipped this came out, it was tinged pink and mucus. And I had to while 5-6 times because so much came out of me!😳😳

Did I just lose my mucus plug?! Or have the bloody show??? The only time before I remember losing it was after my water broke.

I am also very cramping right now with tail bone and back ache.

***** UPDATE ****

Not long after I posted this my water broke, when I got to the hospital I was only still 1cm dilated. And they just checked me again and I’m now 3cm dilated and contractions are every 1-3 minutes apart.
