idk i was fine last night we had sex around 2 am and i was fine up until 11 am that i woke up this morning! and yes it hurts to walk!! :-/
mine is the same right now and I'm 21 weeks had sex with my babies father a few days ago. it's very irritated I hate it. I'm not sure if it's normal but I do know it's so easy to get yeast infection and utis from regular sex while pregnant and that may be the cause. Idk but I feel ur pain =/
With all the extra blood flow we have going on now it's normal. How long has it been swollen? I would say if it doesn't go down after a few hours to call your doctor.
