Hi Jass
Your plug often looks like snot (sorry) often but not always with blood streaks in it and your plug dies regenerate. Being able to fill 2 specimen jars sounds like quite a lot so I suspect that what you are seeing is parts of your plug and some cm (cm increases late in pregnancy). Finding your cervix can be quite difficult especially if you are trying to find it for the first time. It should feel like a long tube or perhaps a little like a volcano. A soft cervix would feel a little like your ear lobe and a hard cervix a little like the tip of your nose. A normal cervix is around 5cm long.
So now to answer your question.
I think labour will start any day now. In fact I can tell you exactly when your baby will be born.
