if i stop taking desogestrel (i’m trying to get a doctors appointment but there isn’t any for two weeks, so i’m contemplating just stopping) can i just start retaking them again with the same packet i’m on now?

Randomly stopping like that means you will spiral your body into withdrawal and then a new adjustment phase. This can cause unwanted side effects. Ring your doctors office or pharmacist for an emergency refill until you can get your appointment.
