Hi everyone, I had a question about vaginal mucus.

here's the problem----

When I get sick or my allergies/sinus are acting up the mucus that gets swallowed has to go somewhere right? well I have excessive mucus in my vagina when this happens, is this the result of swallowing mucus. I have been tested for all STD's twice, and I am clean. I would just like to know, I don't have any other symptoms other than I have a  slight amount of discharge and sometimes have to wear a liner. if anyone could answer either or both of these questions that would be great thanks :)
