What Can Cause Pink Discharge Around Clitoris?

I've been having a slight pink discharge around the clitoris. It looks a little like phlem. I'm 37 and was having this at least once a month for the past 8 months, but in the past month, i've been getting it almost ongoing, maybe skiping a day or so. Can you please help. I have an appointment on the 9th of this month with my gyno.
