why are my periods late

There are several reasons why your periods might be late and, given the negative pregnancy test, we can consider other factors. Stress is a common cause that can indeed disrupt your menstrual cycle, as can changes in weight, and lifestyle—both weight gain and loss can affect hormonal balance. Talking about hormones, conditions like Polycystic Ovary Syndrome (PCOS) or thyroid imbalances can also lead to irregular periods. The fact that you’re experiencing fatigue and moodiness could possibly relate to hormonal fluctuations, including thyroid issues, so testing your thyroid function could be worthwhile. It’s great you’re considering a visit to your doctor as they might suggest running tests like a thyroid function test, prolactin level check, or an ultrasound if there’s a suspicion of conditions like PCOS. Remember, certain medications, intense exercise, or even the approach of menopause can also cause changes in your cycle. If your period doesn’t arrive within another few weeks, it’s a good idea to follow up with your healthcare provider. Meanwhile, try to minimize stress and maintain a balanced diet. Take note of any additional symptoms you experience, as they can offer clues to your doctor. If there’s any sudden pain or unexpected symptoms arise, seek attention more urgently. Keep track of your cycle and symptoms for patterns or changes that you can discuss at your next visit.
