Is yellow vaginal discharge a cause for concern?

Hello, is the yellow, odorless, unabundant vaginal discharge of viscous consistency a cause for concern? No pain during intercourse, itching, possible occasional slight burning during urination. I read that the yellow color of the secretion may mean trichomoniasis, but the consistency and smell of vaginal discharge are completely different from those accompanying it. Such fears only take place for a few days, should I wait or go to the doctor? (I've been using hormonal contraception for a few years, if that would matter.)
