Start with your usual pattern
A cycle diary helps show whether the timing or amount of bleeding has changed. Record the first day, duration and symptoms. Note contraception or medicine changes around the same time.
Several causes can look alike
Pregnancy, contraception, weight changes, thyroid conditions and changes in ovulation can affect timing. Age matters too. A clinician can use your history to narrow down which causes should be considered.
What to discuss at an appointment
Mention any bleeding between periods, new pain or bleeding that disrupts daily life. The clinician may suggest a pregnancy test, blood tests, imaging or an examination depending on the pattern.
Act promptly for concerning symptoms
Very heavy bleeding with faintness or breathlessness warrants urgent care. Bleeding after menopause should be evaluated promptly. If pregnancy is possible and you have severe pain or fainting, seek urgent help.
