Heavy period for 2 weeks: what to know

A period that continues heavily for 2 weeks may happen when the uterine lining is not shedding in a regular pattern. Possible causes include fibroids, adenomyosis, endometrial polyps, endometrial hyperplasia, hormonal changes around perimenopause, and polycystic ovary syndrome. Pregnancy-related bleeding and some medicines also need consideration.

The duration and flow both matter. Prolonged loss can leave you tired, light-headed, short of breath, or unable to manage usual activities. These symptoms can point to iron deficiency anaemia, even when pelvic pain is mild.

Book a prompt appointment with a doctor or gynaecology service. Bring a list of medicines and contraception, note the date bleeding began, and describe the heaviest days, clots, pain, and any chance of pregnancy. Do not start iron or hormonal treatment without advice tailored to you; testing may be needed to identify the cause and check your blood count.

Go to emergency care if you are soaking protection repeatedly, passing very large clots, fainting, becoming confused, or developing severe pain, chest discomfort, or breathlessness. If pregnancy is possible, heavy bleeding with one-sided pain or faintness needs immediate assessment.

Ask whether you need a pregnancy test, blood count, iron testing, pelvic examination, or ultrasound, and how to manage bleeding while the cause is being investigated.
