What should I do? Is it nothing?

Er

All night lastnight when I would try to get out of bed to pee or get a drink, my pelvis hurt like my legs were spreading too far. When I’d walk it was very difficult. Almost like pressure. I have suffered with SPD but this feels different. All day today it still is sore and awkward to walk. It feels like something is in my vagina or just heavy on my cervix and falling out. I also feel lightning which I know is from her head pressing down. I haven’t noticed any contractions but I may also have not really been focusing for any. I’m 41+3 and scheduled to have an induction tomorrow night. Could this just be dilating more? I saw a very small, almost nonexistent, piece of what may have been mucous plug (stretchy like fertile cm) on my tp after wiping. I’ve been nauseous on and off the last few days. Now that I’m kind of thinking about it, i do keep feeling like I need a BM but then nothing comes out. My belly feels a bit like gas pains on and off but I almost don’t even notice it. Last week my cervix was still closed and I was effaced to 70%
