What should you know about first year of period irregular?

After the first period, ovulation may not happen in every cycle, so bleeding can arrive at changing intervals or be absent for a while. Stress, changes in weight, intensive exercise, illness and some medicines can also affect timing. Ongoing irregularity may be associated with anovulation, polycystic ovary syndrome or, less commonly, premature ovarian insufficiency. Perimenopause is a different life stage and is not the usual explanation for a newly menstruating teenager.

Use a calendar or period app to record bleeding days, flow, pain, acne, excess hair growth, dizziness and missed cycles. Carry suitable period products and tell a trusted adult if bleeding interferes with school, sleep or activities. A clinician may ask about pregnancy possibility, nutrition, exercise, stress and medicines before deciding whether an examination or blood tests are needed.

Arrange medical advice for very heavy bleeding, repeated prolonged episodes, severe pain, faintness, unusual tiredness, or long gaps between periods. Seek urgent help if bleeding is soaking through protection rapidly, you feel faint, or pain is severe. Earlier review is also sensible when irregular periods occur with marked acne, new facial hair, milk discharge, headaches or vision changes.

Ask what pattern is expected at your age, whether your symptoms suggest anovulation or polycystic ovary syndrome, which tests could help, and whether treatment such as the Combined Pill or Metformin for PCOS is appropriate for your situation.
