Honestly, I would just use it once a day because that is what I did before and it worked AMAZINGLY, but if you use it twice a day like I tried yesterday, I noticed that my teeth/gums are a little sensitive now....I'd say just go with once a day.

A publication that's published every two months is a bi-monthly. That would be six issues per year. There was some abiguity in the past with the term sometimes being used to mean both twice a month and every two months. There was a gradual shift in the late twentieth century to that term being used to indicate every two months.
there are 12 months in every Gregorian year.
Q3M (quaque 3 months) is one format, but this is not a common abbreviation. It is more likely that the notation would be to perform the treatment "quarterly", which would be every 3 months. The trend is going away from abbreviations, so that the order for every 3 months is clear to anyone who might have to look at a patient's chart or health record.
Quarter. At every Quarter of the financial year (every 3 months).
