It is very common to experience bleeding or spotting about seven days after taking the I-pill (levonorgestrel). This emergency contraceptive contains hormones that temporarily alter your menstrual cycle, often causing what is known as withdrawal bleeding. This is a normal response and typically indicates the medication is working. Keep in mind that your next regular period may arrive a few days earlier or later than expected. If your bleeding becomes exceptionally heavy, is accompanied by severe lower abdominal pain, or if your next period is delayed by more than a week, please consult a healthcare professional just to be safe.
