20w and several times over the last few weeks I’ve had sensations inside my belly when I stretch or sit a certain way that feels like when a ladder runs on a pair of tights. Yes I know that sounds batshit! It’s not painful as such but it almost feels like a whole stretch mark is coming up all at once.. but internally? It makes me nervous as it’s a weird pinging sensation that often freaks me out as you do get a pinging feeling right before your waters break! Can anyone relate? Or am I just mad?
