Vagina pressure?

Lauren • On baby #2. I've got my boy & now I've got my little girl on the way. Couldn't be happier 💛
I am 24 weeks pregnant with my 2nd child and I feel like every time I have laid down for a long period of time resting it's hurts to get up, like my vagina is so sore from pressure or something. It's usually in the mornings after waking up an I try getting out of bed. Has anyone else experienced this or something similar? Why does it happen?
