what can be the reason for late periods

A lot of things can lead to late periods, and it’s not unusual to be puzzled when your cycle unexpectedly shifts. Stress certainly can contribute, but there are many other potential factors. Changes in your routine, like traveling and eating differently, often disrupt your body’s rhythms. Starting a new workout regimen can also affect your menstrual cycle, especially if it’s a significant change from your previous activity level. This is because exercise can impact your hormone levels and overall energy balance, altering your period timing. Birth control or any recent changes to it could also influence your cycle. Vitamins generally don’t delay periods, but if they have hormonal effects or are changing your body’s balance, it might play a role. Also, sudden weight changes, whether loss or gain, can affect your hormone balance and menstruation cycle. Conditions like polycystic ovary syndrome (PCOS) or thyroid issues can disrupt regularity too, regardless of weight changes. In your case, since you’ve taken pregnancy tests that are negative and given the circumstances with traveling and exercise, it’s likely a combination of lifestyle factors. However, if your period doesn’t come in a couple more weeks or if this becomes a recurring issue, it would be a good idea to consult with your healthcare provider. They can run tests to rule out conditions like thyroid dysfunction or other hormonal imbalances. It may also be helpful to maintain a cycle diary, noting any changes in lifestyle or stress levels so that you and your doctor can address possible causes more effectively. For now, focus on restoring balance, regular sleep, and a stable routine. If symptoms persist or if you have concerning changes, seeking medical advice is the best course.
