If 1 pill is missed (at any time in the cycle)

-the women should use condoms or abstain from sex until she has taken pills for 7 days in a row. FSRH: ‘This advice may be overcautious in the second and third weeks, but the advice is a backup in the event that further pills are missed’
if pills are missed in week 1 (Days 1-7): emergency contraception should be considered if she had unprotected sex in the pill-free interval or in week 1
if pills are missed in week 2 (Days 8-14): after seven consecutive days of taking the COC there is no need for emergency contraception*
if pills are missed in week 3 (Days 15-21): she should finish the pills in her current pack and start a new pack the next day; thus omitting the pill free interval
