A member asked:
Why did my cycle go from 35 to 39 to 31 days? is that normal? i have a period every month
A doctor has provided 1 answer
Normal Range: A menstrual cycle can still be considered normal if it is around 28 days between the first day of your periods. Some women have longer cycles (that are normal) of up to 35 days between periods. There can be normal variations of a few days (longer or shorter) without worry. This does not sound like a problem.
