A missed or delayed period can happen for several common reasons, even if pregnancy is not a possibility. Changes in routine, stress, weight gain or loss, travel, poor sleep, or recent illness can temporarily affect your hormones and delay your cycle. Hormonal conditions like Polycystic Ovary Syndrome or thyroid imbalance can also lead to irregular periods, especially if this happens repeatedly. Sometimes, it may just be a one-time delay, and your cycle may return to normal on its own. For now, try to maintain a healthy routine with a balanced diet, regular exercise, good sleep, and stress control. However, if your period does not come within a couple of weeks or if you continue to have irregular cycles, it is best to consult a doctor for a check-up. Avoid taking any tablets on your own to induce periods, as the treatment depends on the underlying cause.
