I am now about 29 weeks and over the last couple of weeks have noticed that the outer lips of my vagina are swelling up. They are not painful, but a little bit uncomfortable. No other symptoms at all. It is not all the time and they do change throughout the day. Has any one else experienced anything similar in pregnancy? Is it anything to be worried about or is it to do with increased blood flow and pressure? Seeing my doctor in a week so will ask him then, but hoping for some reasurance in the meantime! Thanks :)
