Menstrual issues


Doctor, may I ask if it's normal to have a bit of brown discharge before menstruation? What does it mean, and does it indicate that my period is coming? In January, I received a menstrual induction injection, and my period started on the 22nd.
I didn't have my period in February.
The cycle from December to January was 50 days, and it has been 39 days from the end of January to today.
When can I expect my period to arrive?

Niming, 10~19 year old female. Ask Date: 2023/03/01

Dr. Cao Guotao reply Obstetrics and Gynecology


Hello, it is recommended to go to the hospital for a blood test to check if your hormone levels are normal.
Wishing you good health.

More Info


Brown discharge before menstruation is a common occurrence that many women experience. This discharge is typically a sign that your period is approaching, and it can be attributed to several factors related to the menstrual cycle.

Firstly, the brown color of the discharge is usually due to the presence of old blood. When menstrual blood takes longer to exit the body, it can oxidize, turning a brownish color. This is often seen at the beginning or end of a menstrual period, but it can also occur in the days leading up to menstruation. The discharge may also contain cervical mucus, which can vary in consistency and color throughout the menstrual cycle.

In your case, you mentioned that you received a hormone injection to induce menstruation in January, and your cycle has been irregular since then. A cycle length of 50 days in December followed by a missed period in February indicates that your menstrual cycle may be experiencing some fluctuations. It’s not uncommon for women to experience irregular cycles, especially after hormonal treatments, stress, changes in weight, or other lifestyle factors.

Regarding the timing of your next period, it can be challenging to predict exactly when menstruation will occur, especially with a history of irregular cycles. The average menstrual cycle lasts about 28 days, but cycles can range from 21 to 35 days in adults. Since you have had a 39-day cycle since your last period, it is possible that your period could arrive soon, especially if you are experiencing brown discharge, which often indicates that your body is preparing for menstruation.

If your cycles continue to be irregular or if you experience any concerning symptoms such as severe pain, heavy bleeding, or significant changes in your discharge, it is advisable to consult with a healthcare provider. They can perform a thorough evaluation, which may include a physical examination, blood tests, or imaging studies, to rule out any underlying conditions such as hormonal imbalances, polycystic ovary syndrome (PCOS), or other reproductive health issues.

In summary, brown discharge before your period is generally a normal sign that menstruation is approaching. Given your recent history of irregular cycles, it may be helpful to track your menstrual patterns and any associated symptoms. If you have concerns about your menstrual health or if your cycles do not normalize, seeking medical advice is a prudent step to ensure your reproductive health is on track.
