Menstrual issues


Doctor, I would like to ask if it is normal that my period hasn't arrived this month, considering that it was from June 11 to June 17, July 19 to July 25, August 19 to August 25, September 25 to October 1, and October 26 to November 1.
What is the approximate length of my cycle? Is my menstrual cycle considered regular? Today I have some lower abdominal pain; does that mean my period is about to start?

Niming, 10~19 year old female. Ask Date: 2023/11/29

Dr. Cao Guotao reply Obstetrics and Gynecology


Hello, you should be fine; just keep an eye on it.
Wishing you good health.

More Info


Understanding menstrual irregularities can be quite complex, as each woman's cycle can vary significantly due to a multitude of factors. Based on the dates you provided, let's analyze your menstrual cycle.

Your reported menstrual periods are as follows:
- June 11 to June 17
- July 19 to July 25
- August 19 to August 25
- September 25 to October 1
- October 26 to November 1
From this data, we can calculate the average length of your menstrual cycle. The cycle length is typically calculated from the first day of one period to the first day of the next period. Here’s how the intervals break down:
1. From June 11 to July 19: 38 days
2. From July 19 to August 19: 31 days
3. From August 19 to September 25: 37 days
4. From September 25 to October 26: 31 days
5. From October 26 to November 1: 6 days (as of today, November 1)
Now, if we average the cycle lengths (excluding the last short interval since it is incomplete), we have:
- (38 + 31 + 37 + 31) / 4 = 34.25 days
This suggests that your average cycle length is approximately 34 days, which is slightly longer than the typical cycle length of 28 days. However, cycles can range from 21 to 35 days and still be considered normal.
Regarding the regularity of your cycle, it appears that while you have some longer cycles, they are relatively consistent in their length. A cycle is considered regular if it varies by no more than a few days from month to month. In your case, the variation between 31 and 38 days indicates that your cycles are somewhat irregular, but not excessively so.

As for the abdominal pain you are experiencing, it could be a sign that your period is approaching. Many women experience premenstrual symptoms, including cramping or discomfort in the lower abdomen, which can occur a few days before menstruation begins. However, this is not a definitive indicator that your period will start soon, as some women experience such symptoms without menstruation following.

If your period does not arrive soon, it may be worth considering other factors that could affect your cycle, such as stress, changes in weight, exercise habits, or underlying health conditions. If you find that your cycles continue to be irregular or if you experience significant discomfort, it would be advisable to consult with a healthcare provider. They can perform a thorough evaluation, including a physical examination and possibly hormonal testing, to determine if there are any underlying issues that need to be addressed.

In summary, while your cycle is slightly longer than average and shows some irregularity, it is not uncommon. The abdominal pain you are experiencing could indicate that your period is on its way, but it is not a guarantee. Monitoring your cycle over the next few months and discussing any concerns with a healthcare professional will provide you with the best guidance for your reproductive health.
