Swollen!!

Nala
Help mommies to be I'm almost 30 weeks and suddenly my vaginal region began swelling on one side it's so sensitive to touch and sore but no indication it's a bacterial infection and sex just makes the swelling even worse! I do have horrible fluid swelling from toes to mid upper thigh from working on my feet all day and could that be a reason I've also heard of vulva Vericos veins! Has anyone else had this or had this please help I'm in pain and feel bad bc hubby wants to touch but it hurts way too much
