I took the birth control pill 1 hour late?
If you're on the progestin only pill ("minipill", such as
Micronor, NoreBe, or Cerazette), you should use a backup method of
birth control if you're more than three hours late. Us the backup
method for the next two days after the late pill (or 14 days if you
took ulipristal for emergency contraception).
If you're on the combination (regular) birth control pill, you
don't need to worry about a backup method unless you're more than
24 hours late.
