vagina questions, no pictures, but tmi

So I've had a bad cough for a couple of weeks. For the last week, when I cough it feels like there's something in my vagina. A few days ago I felt in there, seemed normal. Today I decided to bust out a hand mirror and look. It looks like there's just a lot of stuff inside. Like I can see no discernible hole, just a bunch of puffy stuff. Is this normal in pregnancy?? Sometimes I feel like my vagina is going to turn inside out! No rude comments please, I don't look inside my vagina often (or ever) so I can't truly say how different it looks.
