A member asked:
Help! is 20-21 days in between my period too short or normal compared to other women?
A doctor has provided 1 answer
24 days: 24 days is the shortest cycle length that is considered normal. The cycle length counts from the first day a menstrual period starts with the slightest spotting and ends the day before the next cycle. If a woman has 20 days between the end of her bleeding and the next bleeding, the bleeding would have to last 4 days to make the entire cycle 24 days.
