What to Know About Irregular Periods for 2 Months

A cycle may become longer, shorter, missed, or unpredictable after stress, illness, weight change, altered exercise, travel, or a change in hormonal contraception. Pregnancy and hormone-related conditions are other possibilities, and the pattern alone cannot identify the cause.

Irregular bleeding can reflect a temporary shift in ovulation. With anovulation, an ovary does not release an egg during a cycle, so bleeding may be delayed or arrive unpredictably. Polycystic ovary syndrome may present with irregular or absent periods alongside signs such as acne or increased facial or body hair.

Perimenopause may present with changing cycle length, altered flow, hot flushes, or sleep changes. Premature ovarian insufficiency may present with irregular or missed periods before the expected menopausal transition. Thyroid problems, some medicines, and hormonal contraceptives can also change bleeding. A clinician uses your age, pregnancy possibility, symptoms, medicines, and previous cycle pattern to narrow the explanation.

If pregnancy is possible, take a home pregnancy test according to the kit instructions. If the result is negative but your period still does not arrive, repeat the test at the time advised by the kit or contact a healthcare professional. Seek medical advice promptly for a positive result accompanied by bleeding or pain.

Record the start and end of each bleed, whether the flow is light or heavy, clots, pelvic pain, bleeding after sex, and symptoms such as hot flushes, acne, hair changes, weight change, tiredness, or nipple discharge. Also note contraception, medicines, recent illness, exercise changes, and stress. Do not start hormonal tablets or someone else's medicine to trigger a bleed; treatment depends on the cause and whether pregnancy is possible.

Arrange a routine appointment if the irregular pattern continues, repeatedly returns, affects plans for pregnancy, or comes with bleeding between periods, bleeding after sex, new hair or skin changes, hot flushes, or persistent pelvic discomfort. Assessment may include a pregnancy test, discussion of medicines and contraception, an examination, blood tests, or an ultrasound, depending on your situation.

Get urgent medical help for sudden or severe pelvic or abdominal pain, especially with a positive pregnancy test or possible pregnancy. Go to emergency care for fainting, marked dizziness or weakness, shoulder-tip pain, trouble breathing, or bleeding so heavy that you are soaking through period products rapidly. These warning signs need prompt assessment because significant blood loss or a pregnancy outside the uterus may require immediate treatment.

You may want to ask: Could contraception or another medicine explain this change? Do my symptoms suggest that I am not ovulating? Should I have a pregnancy test, hormone or thyroid blood tests, or an ultrasound? What treatment fits my goals if I want contraception, symptom control, or pregnancy? Ask what changes should prompt an earlier review and how long to keep a cycle record.
