... there was any harm in using it during the day. Well now the ointment is leaking out. Will it still work, or can I use Monistat 7 tomorrow after washing out Monistat? Or should I wait 7 days and see what happens? Also tomorrow when I take a shower, should I wash the Monistat out of me? Should I wait 7 days before having sex again? This is my first yeast infection and I have zero time to see my gynecologist
