How does the emergency contraceptive pill (i-pill) work, what are its typical side effects, is it normal for menstruation not to occur within three days of consumption, and what are the physiological effects if it is taken without prior sexual intercourse?
The i-pill (levonorgestrel) works primarily by delaying ovulation to prevent pregnancy. Common side effects include temporary nausea, headache, fatigue, or mild abdominal pain. It is completely normal not to menstruate within three days of taking it; her next period may simply be a few days early or late. If taken without prior intercourse, it won't cause lasting harm, but it introduces unnecessary hormones that can temporarily disrupt her natural menstrual cycle. Please reassure your partner that these hormonal fluctuations are common and temporary. If her period is delayed by more than a week, a simple pregnancy test is recommended.
