It's quite possible you developed a mild yeast infection from the antibiotics.
I recommend you take a bath and add 1 cup of white vinegar and 1 cup of epsom salts. Do not use soaps. In general, soaps can be hazardous to your vaginal canal. So stop using them completely and rinse only with water.
Also, very important, start ingesting large doses of Pro-Biotics, to offset the antibiotics and also start eating Organic Apple Cider Vinegar on salads, avocados, etc.
