Ok so I'm pretty sure I have a yeast infection but not one that's very serious. I just started monistat 7 Sunday night and my bf and I were planning on spending next weekend together an more than likely were going to have sex. The treatment is over with on Saturday night and I was wondering, is it absolutely necessary, that I have to wait seven days after the treatment for us to have sex if we use a condom because I have a back up birth control device and merely want to use the condom so he doesn't get an infection as well?
