Do I have to stick to a fixed day for the injection?

I am looking into Wigobi, and I am wondering how to manage business trips or travel schedules if the system operates on fixed days of the week.

My schedule tends to be irregular, so I would like to know if there are criteria for changing the administration dates, and if I should arbitrarily adjust the intervals.

I am curious about what difficulties actual users have experienced with schedule management, and regarding changes to the administration date, it is appropriate to check with the prescribing medical team, right?
