Concerned about yellow leaves

My Neon Pothos is ~6 years old and has never had problems until ~2 weeks ago. Starting to get lots of yellow leaves. I water her every other week (she droops when she wants water), 70 degrees F in the apartment (she’s lived here for the last 3 years). Any ideas what might be wrong? I’m worried!
