Although it's difficult to get on mucus glands, it is possible to get poison oak on your vulva. It's difficult, I believe, to get it internally. If you have a bad case, there will be a LOT of clear ooze coming from your vagina. Also, it will be very inflamed and swollen. If this should happen, see a dermatatologist.

Yes. You may notice that you have more mucus in between your cycles. That is ovulation, and the increased mucus is to aid the sperm in fertilizing the egg. After ovulation happens, the vagina doesnt need to be as moist, b/c there is no reason it needs sperm to travel. Its normal.
The vagina is like before pregnancy but the cervix, the opening to the uterus, is closed by a mucus plug.
