Why does my vagina hate me?!?!

Brittany
Ok so I just got rid of a yeast infection about a week ago. Now I have ANOTHER one. I'm real itchy and having a greenish clumpy discharge and that freakin smell is back! Is there something I'm doing that could be causing this or could I have given my husband a yeast infection before I knew I had one and when we had sex he gave it to me again?
