iv not had sex in months but last night i had yellow discharge, it doesn't smell and it hasn't happened before, it doesnt itch, at points there was a lot and was watery, other times during the night it was thick and noticeably yellow. help?

Sounds like a bacterial infection or std of some kind. vagasil has a test. It wil tell you what your ph level is. And wether or not u need to see a GYN. I recommend going to the doctor or clinic ASAP. Good luck
