Kourtney takes Logynon ED. She missed her pills only on day 1, 14 and 24 and had sexual intercourse on day 25. Does she need EHC?
no – 7 days’ worth of cover after day 1, built up cover. Missed one at day 14 but hasn’t missed 2 in a row and hasn’t had sex. Day 24 is a placebo pill so doesn’t make a difference
