You might be suffering from a vaginal yeast infection. Developments can take place in women who have such conditions, even in the days following the period. They are defined by the secretion of non-fatty material, unpleasant sensations of the vagina, and the small labia swelling. To relieve the infection use over-the-counter creams for yeast. Don't forget to keep the location clean and dry. Consult a gynecologist for proper treatment.
