Movisse is a norethindrone mini so it has a 3 hour window, so you need to be very strict about taking it on time. Think about when’s best for you to take it, ideally a time that will suit you the majority of the time, during the weekdays and weekends.
I also recommend learning how exactly your pill needs to be taken, what are the potential side effects so you know what’s happening if you get them, what can affect it’s effectiveness and what you need to do when you miss a pill. Education is key.
