Possible TMI..Anyone else feel this?

Rebecca
I don't remember feeling this with my first. I'm 26 almost 27 weeks with my second. Every time I sit on the toilet to do either 1 or 2 it feels like my vagina is opening or like there is pressure or that it's swollen. Has anyone else felt this? As I'm writing this I'm relaxing on a recliner and I'm starting to feel it again.
