Very swollen down there? Not sure what to do


Last few days it’s felt a bit dry down there but nothing concerning so I let it go. today is like literally throbbing and it’s super swollen to the touch down there. I’m 38 weeks atm, not sure what’s going on, or does this usualy happen? Like I’m stressed on how swollen all the lip area looks. Sex was even painful today so I just couldn’t do it .

Sorry TMI
