I'm thinking of changing the time I take my pill. Normally it's 10am, how would I safely go about changing it to taking it at night time? I'm on desogestrel and it's got a 12 hour window

If it’s within 12 hours of your current time you can just start taking it at your new time. If it’s outside 12 hours, you could take it some time in the afternoon one day, like 3pm for example, and then take it at your desired time the following day, eg at 11pm

Thank you! @bluerose9
