can you feel thinning of cervix?

Just curious! 3rd baby, first time feeling like this. It's not lightening crotch btw! 
My baby is very low (midwife even commented on how low) and tonight when he kicks i get a pinching type pain in my vagina, like I want to hold it 😂 it's hard to describe, like its a pinch but it feels like I'm gonna pee also. Even when I've just been. 
Do you think this could be thinning of the cervix? I'm only 31+2 but have both my other babes between 36-37 weeks and was dictated to 3-4 for 2 weeks before hand. Just curious!
