Okay so I am getting ready to start monistat for a yeast infection. I know that it is recommended that you eat yogurt while on the medication to replace the good bacteria that is lost with the treatment. My question is does anyone know how many times a day I should eat the yogurt and how much. Also can you use monistat if you are on your period. I am "supposed" to start tomorrow (might be pregnant) so I just need to know asap because I will start the monistat tonight if I can.
