Question: Female cycles

 Yvonne - Wed Jul 07, 2004 9:29 pm

What is the normal days for the female cycle if the period only lasts on an average of 4 days? Is it still 28 days? or does it change when you have cycles more like 7 days long?

Thank you,

User avatar The menstrual cycle is not the same for every woman. On average, menstrual flow occurs every 28 days and lasts about 4 days. However, there is wide variation in timing and duration that is still considered normal, especially if your periods began within the last two years.

If you soak through a sanitary pad or tampon every hour for 6 consecutive hours, this is considered a very heavy period. A prolonged period is one that lasts longer than 7 days. Irregular periods happen more often than every 21 days or less often than every 35 days.
