Hello, I understand your concern. It is very probable that you are experiencing symptoms of a yeast infections. This kind of infection is quite common after a course of antibiotic treatment, due to the fact that antibiotics kill the good bacteria in the genital tract, causing the yeast germs to outgrow in number, thus messing up the balance between the good and the bad bacteria. Some of the most common signs of yeast infections (candidiasis) are itching, burning, vaginal discharge which can be quite thick, pain during sex and rash. Keeping the area dry after each bathroom trip and applying an over the counter topical antifungal medication should solve the problem. Wishing you all the best
