Bleeding Between Periods and Hormonal Imbalance

Changes in oestrogen and progesterone can disturb ovulation or make the womb lining shed at an unexpected time. Hormonal contraception, missed doses, stress, weight changes and life-stage transitions can also alter the pattern.

Light spotting can occur when ovulation is irregular, yet bleeding alone cannot confirm a hormonal imbalance. Pregnancy-related bleeding, infection, cervical changes, endometrial polyps and uterine fibroids can produce a similar symptom.

A clinician may consider the timing, flow, contraception, medicines, pregnancy possibility and symptoms such as pelvic pain or unusual discharge. Depending on that history, assessment may include a pregnancy test, examination, blood tests, infection testing or imaging.

Record when bleeding begins, whether it is spotting or a period-like flow, how often protection needs changing and any pain, discharge or bleeding after sex. Note new medicines, missed contraceptive doses and the date of your last expected period.

Take a home pregnancy test if pregnancy is possible. Arrange a routine appointment if the bleeding repeats, lasts beyond the expected pattern, appears after sex or is accompanied by pelvic symptoms. Do not start hormone products solely to stop the bleeding without clinical guidance.

Seek urgent medical help for heavy bleeding that rapidly soaks through menstrual protection, fainting, marked dizziness, weakness, severe or one-sided pelvic pain, shoulder-tip pain, or bleeding with a positive pregnancy test. Fever with worsening pelvic pain or foul-smelling discharge also needs prompt assessment.

Ask whether your pattern fits irregular ovulation, whether pregnancy or infection testing is appropriate, and whether your contraception or another medicine could be contributing. You can also ask what change in flow or pain should prompt urgent review.
