My vagina is in pain when I walk squat & when anything is tightly fitted. It's been like this for 3 days. I was cleaning my vagina & was inspecting it. When I open the flaps and bring them up a round bubble looking bump pops out of what I think is my pee hole.. What is this??? It happened after I had been on my period & wore pads. It was very hot temperatures the week of my period.
