Vaginal swelling

I'm almost 31 weeks pregnant and my vagina is swollen! First it started out on my pubic area and today I noticed it moved a little more south. The swelling on my pubic area is still there. Also, when I lie down for a long period of time and get up, the swollen parts hurt. I talked to my dr and she said it was normal but didn't bother to look or anything. It's been about a month now and it hasn't gone down, is this actually normal?
