What factors influence when your period is?

Several factors can influence the timing of your menstrual period, including hormonal fluctuations, stress levels, diet, exercise, and underlying health conditions. Age and life stages, such as puberty or perimenopause, also play significant roles in menstrual regularity. Additionally, changes in weight or significant lifestyle alterations can impact your cycle. Overall, each individual's menstrual cycle can vary widely based on a combination of these factors.
