The organism usually referred to as yeast is almost always present on everyone's body. It is when it gets out of control that it causes problems. As long as the symptoms last and you are still medicating avoid sex or, at least, use a condom. It is possible while you are both treating to pass it back and forth.
If she uses over the counter treatment, she needs only a few doses inserted into the vagina. Different brands call for different applications. This is nothing to upset her mother. Women, and sometimes men, develop various fungal infections whether or not they are sexually active.
With respect to the "gone" await her treatment so that it is "gone" in both of you. You can share yeast outside the area of the condom but it grows in damp areas.
