First-Time Spotting Before Your Period

Light bleeding before the expected period can occur when the lining of the womb responds to changing hormones. It may also follow a change in contraception, missed doses, or irritation of the cervix. Chlamydia, cervical dysplasia, endometrial polyps, and uterine fibroids can present with abnormal bleeding. Cervical cancer and womb cancer may also present with unusual bleeding, so repeated or unexplained episodes need evaluation; spotting itself does not identify the diagnosis.

Keep a cycle record showing when spotting starts, how long it lasts, whether it becomes a period, and whether sex causes it. Note cramps, discharge, fever, or dizziness. Take a pregnancy test if there is any possibility of pregnancy. Arrange a routine appointment for a first episode that concerns you, and seek follow-up if the pattern repeats or changes. Bring your medication and contraception details to the visit.

Get urgent help for heavy bleeding, severe pelvic pain, fainting, pronounced dizziness, fever, or bleeding during a possible pregnancy. Seek prompt assessment for bleeding after menopause, bleeding after sex that continues, or discharge with a strong unpleasant smell. A clinician may need to check for infection, pregnancy, anaemia, or changes in the cervix and womb.

Ask what pattern of spotting should be monitored, whether you need a pregnancy or infection test, and whether an examination or scan is appropriate. Explain your usual cycle and any recent contraceptive change.
