Irregular Periods 25 To 45 Days Apart For Six Months, Is That Normal?

Cycles that change from month to month are common and are often linked to stress, weight changes, intense exercise, poor sleep or thyroid problems. Polycystic ovary syndrome (PCOS) is another common cause, especially when irregular periods come with weight gain, acne or extra hair growth.

Keep a simple diary of your period dates for the next three months, aim for regular meals and daily activity, and try to manage stress. Because this has gone on for six months and you have gained weight, it is a good idea to see a gynecologist. Simple blood tests and sometimes an ultrasound can find the cause, and most causes are very treatable. Go sooner if you have very heavy bleeding, severe pain or no period for more than three months.
