Possible yeast infection

I have the odd discharge and itching/burning of yeast infection. I have an appointment with planned parenthood to check and get medication tomorrow at 9:40 am. But I get off graveyard shift at 9. So hopefully I make it. My questions are: 1. Can you have sex with a yeast infection?

2. Will you give it to your partner if you do? (My boyfriend)

3. I recently had a miscarriage and resumed sex once I stopped bleeding. Can the miscarriage have something to do with it?
