Delayed Menstruation: A 37-Day Cycle Concern

Menstrual period is delayed by 37 days?

Hello Doctor, I am currently in the second year of junior high school.
I got my first period in the sixth grade.
I usually have my period about two weeks early, but recently it has been regular, coming every 3 to 4 weeks.
My last period was from December 15 to December 21.
Since then, I haven't had my period.
Last year, there was one instance where my period was 35 days late.
So now I am 2 days late.
Please help me with this issue.
I haven't told my family about this.
Thank you.

The ovarian function is not fully mature during the first 3-5 years after the onset of menstruation, so irregular menstrual cycles can be a normal physiological phenomenon, and there is usually no need for excessive concern.
If you still have doubts, you can ask a family member to take you to a gynecologist for an examination.
However, if you have engaged in sexual activity and your period is more than two weeks late, it is important to consider the possibility of pregnancy.
Additionally, at your age, engaging in sexual activity may be illegal for the other party, and we do not encourage sexual activity among minors.

More Info

Delayed menstruation can be a source of concern for many individuals, especially when there is a noticeable change in the regularity of the menstrual cycle. In your case, you mentioned that your menstrual cycle has typically been around 3 to 4 weeks, but you are currently experiencing a delay of 2 days after your last period ended on December 21. While a delay of a few days can be common, especially in adolescents, it’s important to consider several factors that could contribute to this change.

Firstly, it’s essential to understand that menstrual cycles can vary significantly from person to person and can be influenced by various factors, including stress, changes in weight, physical activity levels, hormonal imbalances, and even diet. For instance, if you have recently experienced any significant stressors, whether emotional or physical, this could potentially affect your cycle. Stress can lead to hormonal changes that may delay ovulation, which in turn can postpone your period.

Additionally, if there have been any changes in your lifestyle, such as increased physical activity or changes in your eating habits, these could also impact your menstrual cycle. For example, excessive exercise or a significant decrease in caloric intake can lead to missed periods or irregular cycles, a condition sometimes referred to as hypothalamic amenorrhea.

Another important consideration is the possibility of pregnancy. If you are sexually active and there is a chance of conception, it would be prudent to take a home pregnancy test to rule out this possibility. Pregnancy is a common reason for a missed period, and if you have any doubts, a test can provide clarity.

If you have ruled out pregnancy and are still experiencing irregularities in your cycle, it may be beneficial to consult with a healthcare provider. They can perform a thorough evaluation, which may include a physical examination and possibly blood tests to check hormone levels. Conditions such as polycystic ovary syndrome (PCOS) or thyroid disorders can also lead to irregular menstrual cycles and may require medical attention.

In summary, while a delay of a couple of days in your menstrual cycle can be normal, especially during adolescence, it is essential to consider various factors that could be influencing your cycle. If the delay persists or if you have other concerning symptoms, seeking medical advice would be a prudent step. Remember, open communication with a healthcare provider can help you understand your body better and address any concerns you may have regarding your menstrual health.
