Yeast infection HELP

24 weeks pregnant and I believe I have a yeast infection. I’m extremely uncomfortable and itchy down there. I was just on antibiotics for bv and I believe that may be what caused it. Anyway, is there something I can do or take to relieve the itch and uncomfortableness tonight until I can get in contact with my doctor tomorrow if they are open? Please help because I’m seriously almost in tears 😭
