Hi, I'm Discharging A Bit More Than I Normally Do.

Hi, I'm discharging a bit more than I normally do. I've noticed it for the past 3 weeks approx. But seems to be a bit more today. It was clear but now it's a bit yellowish/light greenish on toilet paper. But there is no oder. What can this indicate? I'm 47 yrs. old and haven't had a period since March of this year. Could it be due to perimenopause?
