What are the recommended medical steps if menstruation does not occur after completing a five-day course of Crina NCR 10 mg for a delayed period, despite negative pregnancy tests?
Typically, withdrawal bleeding occurs within 3 to 10 days after finishing a course of norethisterone (Crina NCR). Since your pregnancy tests are negative, this delay is often just due to minor hormonal fluctuations, anovulation, or stress. I recommend waiting up to 10 days after your last pill. If your period still hasn?t started by then, please consult your gynecologist. They can perform a simple ultrasound or blood test to check your hormone levels and uterine lining to find the best way forward.
