Hello,
You may not have had yeast. Vaginal odor could be related to vaginal vaginosis, for which there is no OTC treatment, as this is an infection.
I would strongly suggest that you make an appointment with your GYN for an ecam and vaginal culture to provide you with an accurate diagmosis and appropriate treatment plan.
If you have further questions or concerns, please do not hesitate to ask.
Here is some helpful info:
