Normal ovulation mucus...BUT WAIT!!!why isn't it stopping?!!

I'm experiencing normal discharge, but it's lasted now for the last 3 months, only pausing for menstrual cycle, becoming heavier overtime. I'm 30 yrs old. Never been pregnant, not on birth control. Cycles have been irregular. Went 11 months without cycle in 2010-2011. I'm a smoker, not big on exercise or diets.

Why is there so much discharge? How's it not done yet? Where's it still coming from?

Should I be worried?

Could this be the first time I've truly ever ovulated? Can it work like that?
