I have noticed that the right hand side of my inner vagina is swelling when I tense/go to the toilet. It's filling up with blood and turning purple, when I push it in the blood disappears but as soon as I let go it fills back up again. It's not sore at all but it's also very unappealing to look at. When I'm relaxed its fine there's nothing there but when I do the toilet it's filling up. Does anyone know what this could be??
