Spotting for one day then stopping

A small amount of blood may follow ovulation, a hormonal shift, sex, cervical irritation, or a change in contraception. It may also be the beginning of a period that has not fully started. One episode cannot identify the cause, and stopping does not by itself confirm that everything is normal.

If pregnancy is possible, spotting can occur in early pregnancy but can also accompany conditions that need assessment. Bleeding after sex may relate to infection, cervical dysplasia, a polyp, or another cervical issue. Chlamydia is one infection that can cause bleeding between periods or after sex.

Record the date, colour, amount, relation to sex or exercise, and any cramps or discharge. Consider a pregnancy test if your period is late or pregnancy is possible. Arrange a routine appointment if the episode repeats, happens after sex, occurs with unusual discharge, or represents a clear change from your normal cycle.

Use a pad if bleeding returns so you can judge the amount. Do not start or stop prescribed contraception without advice. For a broader explanation of unexpected bleeding, read [Bleeding Between Periods](/symptoms/bleeding-between-periods/).

Seek urgent care for heavy bleeding, severe abdominal or pelvic pain, fainting, marked dizziness, or weakness. If pregnancy is possible, urgent assessment is needed for one-sided pain, shoulder-tip pain, or feeling faint, even if the spotting has stopped. Contact a clinician promptly for fever or pelvic pain with discharge.

Ask whether your cycle history, contraception, or medicines could explain the episode and whether you need pregnancy or infection testing. Ask what recurrence pattern should trigger review and whether cervical screening is due. Share any pain, bleeding after sex, discharge, or recent procedure.
