Its because the vagina has a larger amount of blood flow in it since you became pregnant. The blood flow makes it more delicate and it tends to swell faster, it is supposed to be even more slightly enlarged than normal but its haopened oved the course of our pregnancy that we dont notice. I had this problem til my doc suggested using a genedous amount of lube on both BD and myself.
mines been doing the same thing even if we do it for like 10 minutes it starts hurting and feels swollen when he's done.. and I literally have to put an ice bag on mine
I have pain down there ! My vag and lips like literally feel swollen lol. Sorry tmi but They said its from the pressure of everything pushing down.
Don't be embarrassed. That's what the dr is there for and has heard and seen it all trust me lol. Swelling and pain is normal down there but still tell your dr.
