Monistat 7?

Tiphanee • First time mommy💕👶🏼
So I'm 12 weeks with possible yeast infection, the doctor said it was okay to use but I'm not exactly sure how to put it in do I go all the way up to my cervix and then shoot it or do I touch the cervix and shoot or only go like half way?! They never explained it and I'm so confused also, has anyone had problems or complications with it?'
