**TMI Warning** how do I know if I lost my mucus plug

Hey y’all. So I am pregnant with my second child and this pregnancy has beyond words been different from my first pregnancy and also is taking so much more from my body. With my first I did end up having her 2 months early no reasoning or issues she just decided to make her grand entrance. Before I had her I had no symptoms or clue of labor. I also did not notice if my mucus plug came out of not but I do remember no blood or spotting of any sort. Now with this baby I have a LOT of discharge and I was told it’s not uncommon and that also the fact that I have to get progesterone shots every week also can be a huge factor. Now for the last couple in days I’ve been experiencing a different kind of discharge and at random times. I’m curious if it is pieces of my mucus plug or what else it could be. The only thing I’ve been experiencing for the past couple of weeks is ridiculous vagina pressure bc she is already head down and has been for a while. The only thing that has changed is the pressure now sometimes comes with a terrible pain depending on how I am sitting or laying. When I am standing I don’t have as much of an issue. I am currently 32 weeks exactly and curious if anyone can share any onsite on their experiences with their mucus plug or what their thoughts may be. I also have googled and tried to search imagines myself it’s seems like it’s more common to have darkish or pinkish blood in the discharge which is another reason I’m convinced it might now be my mucus plug.
