I Have Always Had Irregular Periods: What Should I Know?

A cycle can vary when an egg is not released regularly. This is called anovulation. Polycystic ovary syndrome can present with irregular or absent periods, sometimes alongside acne, increased facial or body hair, or difficulty becoming pregnant. Thyroid problems, changes in weight, intensive exercise, stress, and some medicines can also disrupt ovulation.

Age and life stage matter. Irregular cycles can occur in the years after periods first begin and may return during perimenopause. A long-standing pattern is still worth discussing if periods are very far apart, bleeding has changed, or you want to become pregnant.

Record the first day of each period, how long bleeding lasts, how heavy it is, pain, spotting, medicines, and any pregnancy possibility. Bring this record to an appointment. A clinician may ask about weight changes, skin or hair symptoms, exercise, stress, and family plans, then consider a pregnancy test, blood tests, or a pelvic ultrasound according to your history.

Treatment depends on the reason and your goals. Options may include managing an underlying condition or using hormonal contraception to make bleeding more predictable. If pregnancy is possible, take a home pregnancy test rather than relying on cycle timing alone.

Arrange a routine appointment if you repeatedly go months without a period, bleeding becomes heavier or more painful, you bleed between periods or after sex, or irregular cycles are making it difficult to plan a pregnancy. Seek urgent care for very heavy bleeding with weakness, fainting, severe pelvic pain, or possible pregnancy with pain or bleeding.

Ask whether your pattern suggests irregular ovulation, which tests fit your symptoms, whether the uterine lining needs protection when periods are far apart, and how treatment choices would affect contraception or plans for pregnancy. Mention any new pelvic pain, discharge, hot flushes, nipple discharge, headaches, or changes in vision.
