Period coming on day 15

Hello, Anon.

Thank you for your post today.

Occasionally, even women with regular cycles can have a period that comes late or early. An early period can be bleeding just days or weeks after the end of your last period. It can be caused by hormonal and lifestyle changes that disrupt the balance of your body. As long as your period is otherwise normal in flow and duration, I'd not be too concerned. If you find it's happening often, see your doctor.
