Hi everyone. I am 32 weeks pregnant and i am feeling that my vaginal opening is sore since morning. It was perfectly normal uptil yesterday and there was no pain at all. But today i feel heaviness in vagina while walking and mild sore pain at the opening of vagina. What could be the cause? Its my 2nd pregnancy and thank god that, unlike my first i have very little to no pelvic pain this time. But why this vaginal pain today?
