Thanks for providing more information.
As you have history of antibiotics use so it can be culprit of your yeast infection.
As antibiotics disturb normal flora of body while killing infected bacteria resulting in growth of yeast infection.
However as you are suffering from last few months and now partner has some infection.
So firstly your both partners should be treated at same time.
It may be possible that you might have a resistant yeast infection and I would recommend getting tested for Candida glabrata and yeast culture and if you have this then treatment for this would be with Diflucan every other day for 2 weeks, then continue with one pill per day of Diflucan for 4 to 6 months.
And, in addition I would use a Probiotic such as RepHresh PRO B and insert a pill in the vagina daily.
Completely avoid sugar. This also includes white bread, white pasta, cookies, crackers, candy, etc.
Even use of oral probiotics throughout the treatment duration should be considered.
Iodine used topically as a douche is effective against a wide range of organisms including Candida (yeast). Povidone-iodine (Betadine) has all of the advantages of iodine without the stinging and staining.
A douching solution is diluted to one part iodine in 100 parts water ( 1-3 teaspoons Betadine to 1 quart of water) used twice daily for 14 days.
Otherwise it's good to see your gynecologist for proper evaluation,diagnosis and management.
Hope this helps.
