This is not normal and would need a vaginal swab / culture of this fluid for the further evaluation. This can be mild grade of bacterial vaginitis and may need a course of antibiotics. The culture test/swab tells about the causative organisms and also tells about the best antibiotic to work against the infective organism. If you have been exposed to unsafe sex; a STD profile at your local STD clinic would be mandatory.
Please feel free for your follow up questions.
