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

Reduced menstrual duration?

Hello Doctor: I started my menstrual period at the age of 12, and by the time I was 15 or 16, my cycle had stabilized at around 7 days.
However, since I was diagnosed with COVID-19 last year at the age of 20, my menstrual period has varied between 6 to 7 days, and my cycle has often lengthened.
Previously, my cycle was about 28 to 30 days, but now my next period is often delayed by about 5 to 6 days, sometimes even 7 to 8 days, making my cycle exceed 30 days.
I have also taken traditional Chinese medicine for regulation, which has significantly reduced my menstrual pain, but my period feels different compared to before.
Last month, my period started on June 9, and this month it began 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 my usual experience, causing me some concern.
I would like to ask: 1.
Is this change normal? 2.
Since the cycle delay does not exceed 14 days and the duration of the period has not decreased to just 3 or 4 days, should I 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 shorter duration or reduced flow? I apologize for the many questions, and thank you, Doctor, for your answers.

More Info

Understanding changes in the menstrual cycle after COVID-19 is a concern for many individuals who have experienced the virus. Your observations regarding the alterations in your menstrual cycle following your COVID-19 infection are not uncommon. Let's delve into your questions and provide some insights based on current medical understanding.

1. Is this change normal?
Changes in menstrual cycles can occur due to various factors, including stress, illness, hormonal fluctuations, and lifestyle changes. COVID-19 has been associated with a range of physiological changes, including potential impacts on the menstrual cycle. Research suggests that viral infections can lead to temporary disruptions in hormonal balance, which may affect the regularity and characteristics of menstrual cycles. The changes you describe, such as variations in cycle length and flow, can be a response to the stress of the illness, the body's immune response, or even the psychological impact of the pandemic. While some degree of variation is normal, if the changes persist or worsen, it may warrant further investigation.

2. Should you see a doctor?
Given that your menstrual cycle has changed significantly, it would be prudent to consult a healthcare professional, especially if you notice persistent irregularities or if you experience any concerning symptoms (such as severe pain, excessive bleeding, or other unusual signs). While your cycle may not be excessively delayed or shortened, any significant change from your baseline warrants a discussion with a doctor. They can evaluate your symptoms in the context of your overall health and may recommend tests or treatments if necessary.

3. Can intense physical activity affect your menstrual cycle?
Yes, engaging in intense physical activity can influence your menstrual cycle. Strenuous exercise can lead to changes in hormone levels, particularly estrogen and progesterone, which can affect ovulation and menstruation. For some individuals, high levels of physical stress can lead to a condition known as exercise-induced amenorrhea, where periods become irregular or stop altogether. However, moderate exercise is generally beneficial for menstrual health. If you find that intense workouts correlate with changes in your cycle, it may be worth moderating your exercise routine and observing any changes.

In summary, while some changes in your menstrual cycle after COVID-19 can be normal, it is essential to monitor these changes closely. If you experience persistent irregularities or any concerning symptoms, seeking medical advice is advisable. Healthcare providers can offer personalized guidance and support, ensuring that any underlying issues are addressed. Remember, your health is paramount, and staying informed about your body’s responses is crucial for your well-being.
