I've been having yellowish-green vaginal discharge, off and on, for two weeks. there is no unusual itch, pain, odor.

Doctor can check: One's primary care doctor can check out a new or unusual vaginal discharge. The doctor can check for a urine infection, if there are any urinary symptoms. Sometimes vaginal discharges are related to overgrowth of non-dangerous bacteria, but other times they are related to sexually-transmitted infectious microbes that need treatment. A pregnancy test can be done, if needed.
