I had what I thought was a yeast infection. But I've never had one before and I'm 37. On the box it tells you if you've never had one then do not use it, have u had a yeast infection before? I went to my Ob and he prescribed me a topical cream (steroid) for the itching. Was checked for std and he looked under microscope, nothing.... But what he gave me is like an anti fungal cream to put on my lady bits but NOT in the vagina. So go to your Ob.
