How does Crina NCR 15 work, and how many days after finishing a five-day course of taking it once daily should a period start?

Asked by Female, 24 · 13 days ago

Crina NCR 15 contains norethisterone, a hormone that works by mimicking your body's natural progesterone to stabilize the uterine lining. When you finish your five-day course, the sudden drop in this hormone level triggers your body to shed the lining. You can typically expect your period to start within 3 to 7 days after taking your last tablet, though it can sometimes take up to 10 days. Please rest assured this is a very standard timeline, but do reach out to your doctor if it takes longer or if you have any concerns!
