Yeast infection after bv antibiotics

I called my obgyn THURSDAY to send me something in for this itching. I took cleocin for bv and everytime I take an antibiotic I get a yeast infection. He never sent anything and now I’m up a 3 am with the worst itching. Omg wha can I do until I can get some meds on Monday or whenever he decides to send in the prescription. I’m about t cry it itches and burns so bad.

PS monistat didn’t work for me
