Changes in Menstrual Cycle After COVID-19: What You Need to Know

Decreased menstrual duration?

Hello Doctor: I started my first menstrual period at the age of 12, and by the time I was 15 or 16, my cycle had stabilized, lasting about 7 days.
However, after being diagnosed with COVID-19 last year at the age of 20, my menstrual periods have varied between 6 to 7 days, and my cycle has often been prolonged.
Previously, my cycle was about 28 to 30 days, but now my next period tends to be delayed by about 5 to 6 days, sometimes even 7 to 8 days, resulting in cycles longer than 30 days.
I have also taken traditional Chinese medicine for regulation, which has significantly reduced menstrual pain, but my periods feel less normal compared to before.
Last month, my period started on June 9, and this month it started in the afternoon on July 15.
However, by noon today, the flow has already decreased to what I would expect on the fifth day, and the color has turned brown, which is somewhat different from before, causing me some concern.
I would like to ask: 1.
Is this change normal? 2.
Since the cycle delay is not exceeding 14 days and the duration of the period is not reduced to only 3 or 4 days, do I need to see a doctor? 3.
Additionally, if I engage in intense exercise during my period, such as sprinting for 3 to 5 minutes, could this also lead to a reduction in the duration or amount of flow? I apologize for having so many questions, and thank you, Doctor, for your answers.

Understanding changes in the menstrual cycle after COVID-19 is an important topic, especially considering the various physiological impacts that the virus and the stress associated with the pandemic can have on the body. Your experience of changes in your menstrual cycle following a COVID-19 infection is not uncommon, and many individuals have reported similar issues.

1. Is this change normal?
Yes, changes in the menstrual cycle can occur after a COVID-19 infection. The virus can affect the body in numerous ways, including hormonal balance, which is crucial for regulating the menstrual cycle. Stress, whether physical or emotional, can also play a significant role in altering menstrual patterns. The body’s response to illness, including COVID-19, can lead to fluctuations in hormone levels, which may result in irregular cycles, changes in flow, and variations in the duration of menstruation. Additionally, the pandemic itself has introduced significant stressors that can further contribute to these changes.

2. Should you see a doctor?
While your cycle changes do not seem to exceed the thresholds of concern (such as a delay of more than 14 days or a drastic reduction in the number of days of menstruation), it is always a good idea to consult with a healthcare provider if you have concerns. Changes in menstrual patterns can sometimes indicate underlying health issues, and a healthcare professional can provide personalized advice and reassurance. They may recommend tests to rule out other conditions, especially if the changes persist or are accompanied by other symptoms like severe pain or unusual discharge.

3. Does vigorous exercise affect menstruation?
Yes, engaging in intense physical activity can influence your menstrual cycle. Strenuous exercise can lead to changes in hormone levels, which may result in a shorter menstrual period or lighter flow. This phenomenon is often seen in athletes or individuals who engage in high levels of physical activity. If you notice that your menstrual cycle consistently changes after vigorous exercise, it may be worth discussing with a healthcare provider. They can help determine if your exercise routine is impacting your menstrual health and suggest modifications if necessary.

In summary, while the changes you are experiencing in your menstrual cycle following COVID-19 can be attributed to various factors, including the virus itself and the stress of the pandemic, it is essential to monitor your symptoms. If you have ongoing concerns or if your menstrual irregularities worsen, seeking medical advice is prudent. A healthcare provider can help assess your situation, provide guidance, and ensure that your reproductive health remains a priority. Remember, your body has undergone significant changes, and it may take time for everything to return to normal.
