Hey hun. I feel your pain my friend is going through the same problem. I suggest using just cotton undies, don't douche at all, always shower and make sure you dry yourself completely down there. Use dove unscented soap, a mild soap helps I use Jergens. They also have this soap that spanish people mainly use its like clearish yellow, hmm I forget the name but when I remember ill be sure to let you know, I suggest trying that it worked good when I had a yeast infection. Eat plain yogurt once every 3 days. Drink a lot of cranberry juice and water to flush out your infection. Never use lotion, perfume near your cooch. Dont wear your jeans too tight that they give you a camel toe lol but im seriously try to wear jeans that fit well not tight. When you have a yeast infection try to stick to sweatpants. Hope this helps. If it keeps going on seriously talk your mother into how this kind of problem needs to get treated it could be a more serious problem like maybe hyperthyroid, diabetes or anything that needs to be looked at and treated.
