What if I have trouble remembering to change the patch?

Try this: set a reminder on your phone.
Still not working? If you use a reminder system and you are still having trouble remembering, you might want to consider a method that you can forget about for several months or several years. Maybe some types of injectable, an implant or an IUD .
Try a different method: implant, IUD, injectable.
