I have a Strong vaginal odour continuously for a week and half after protected sex How can I fix this?

Vaginal odor. KaraB~ that sounds like a Gardnerella vaginalis infection and a 5 day course of flagyl will fix it. Dare I ask? Is there ANY possibility of retained hardware in the vagina, like a retained tampon or any other foreign body. If you cannot remember please go to a doc and have a vaginal exam to make quite sure. These can be very dangerous if left in thanks.
