29 weeks and really swollen vagina???!

So I’m 29 weeks and yesterday started feeling some pressure and discomfort with my vagina. I didn’t think much of it I thought it was probably because I had been sitting all day. Day two I’m in pain and it’s visibly swollen (inner and outer lips) like it hurts to walk. I see my dr in a little over 24 hours so I really don’t want to have to see anyone else before that. Any ideas on what this might be from? I’ve looked at pictures of vulvar varicosities and it doesn’t seem like that. I’ve tried hands and knees to relieve some pressure and that helped at first and cold washcloth and Tylenol but now nothing seems to be helping and it’s getting worse. 😢
