Is it true that when a month has more than 4 weeks woman should expect to see her cycle week early the next due extra week?

There is no direct relationship between the number of weeks in a month and a woman's menstrual cycle. A menstrual cycle typically lasts around 28 days and is not directly influenced by the duration of weeks in a calendar month. Factors like hormonal fluctuations, stress, health conditions, and lifestyle choices play a bigger role in menstrual cycle regularity and timing.
