Period for one day then stopped

Menstrual flow can vary from cycle to cycle. Changes in sleep, stress, exercise, weight, illness, or hormonal contraception may alter the lining of the uterus and produce a shorter bleed. Pregnancy can cause light bleeding that is mistaken for a period, so consider a pregnancy test if pregnancy is possible. Irregular or absent periods can occur with polycystic ovary syndrome, while menopause changes can gradually space periods out. Premature ovarian insufficiency can affect ovarian hormone production earlier than expected. Turner syndrome is a genetic condition that may affect ovarian development and menstrual function. These possibilities cannot be separated by flow length alone.

Write down the start and stop dates, flow, pain, medicines, contraception, and other changes. Take a pregnancy test if relevant, following the kit instructions and repeating it if advised after an early negative result. Arrange a routine appointment when short or missed periods recur, or when you have symptoms such as new acne, excess facial hair, hot flushes, vaginal dryness, or difficulty becoming pregnant. A clinician may review your history and order hormone tests or other checks.

Get urgent help for severe abdominal pain, fainting, heavy bleeding after a short bleed, or bleeding with a possible pregnancy. Seek prompt advice for a missed period with pain or unusual discharge. The need for care depends on symptoms, pregnancy possibility, and whether the change keeps happening.

Ask whether pregnancy testing or hormone checks are appropriate, whether your contraception could explain the change, and what cycle pattern should prompt further investigation.
