extremely swollen vag (tmi)

Vanessa

i have an extremely swollen vagina. I'm 37 weeks pregnant and it's so swollen and sore I can barely walk.. I, of course, cannot see my own vag at the moment but I had my SO look at it and he could tell right away that it was swollen as my labia usually close around everything and they definitely we're not today. it's also very puffy and red. idk if this is an infection or usual for this late in pregnancy. I have a doctor's appointment tomorrow morning but im curious now as to if it's normal or what. it's just so painful
