What's going on with my CM? PLEASE help

So I have 6 days until my period. I'm typically pretty regular (give or take a day) and my cycle averages at 28 days. Well I've been monitoring my CM and, while normally at this point I'm pretty dry, I have a lot of CM. It's noT cloudy, stretchy, or clumpy. I'm just super wet up there. (No, I wasn't testing after sex or while aroused.) Any idea of what's going on?
