Excessive excretions??

This is so crude to talk about, but I need some insight. I've always ovulated throughout my cycle until my period hit, then had a dry spell for a little less than a week. But what does it mean when you start to have so much excretion that you can't go very long without having to change your undergarments or panty liners? Am I supposed to have to wear panty liners almost all of the time?
