One pill missed (48–72 hours since last pill)Take it now and continue. No extra precautions.
Two or more missed (over 72 hours)Take the last missed pill now. Use condoms for 7 days. Emergency contraception may be needed, depending on the week of the pack.

Progestogen-only pill (POP)

A traditional POP is missed if over 3 hours late (more than 27 hours since the last). Desogestrel has a 12-hour window (more than 36 hours).

Take a pill now and use condoms for 2 days. Consider emergency contraception if there was unprotected sex since the pill was missed.
