Hi, I get the same thing. After the antibiotic therapy, you should try a probiotic like Ultimate Vaginal Flora. It builds up the good bacteria in the vagina and urinary tract. Antibiotics kill ALL bacteria. Therefore, it leaves the vaginal flora imbalanced. Good Luck
Have you gotten treatment for the Infection? If so it is possible that you two are passing it back and forth to one anther..... Also Bacterial Vaginosis is an overgrowth of bacteria and can actually re- occur at any time even with treatment..... The treatment you received might not be strong enough to fight on the infection.... Definitely call the Dr and let him know you are still having issues with this
