Menstrual issues


My menstrual cycle has always been heavy for the first four days (with the second day being the heaviest and accompanied by cramps).
During the day, I usually need to use high-absorbency products.
It typically starts to lighten on the fifth day and lasts about seven days, with very few instances extending to the eighth day.
Although my cycle often comes a week late (I’ve only experienced it coming a week early once), it generally follows this pattern.
However, my April cycle was unusual; my March period started around the 10th, and my April period was a week late, arriving on the 23rd.
When it started, the flow was very light (there were some blood streaks in the toilet and a small amount on the pad).
I experienced the same discomfort as before (cramps on the second day, lower back pain, etc.).
After five days, the bleeding almost stopped (no more blood streaks), but then two days later, I started bleeding heavily again (starting on April 30th).
The flow on May 1st was similar to what I usually experience on the second day, although there was no pain, just a feeling of heaviness.
My daily routine hasn’t changed significantly; I usually go to bed around 11 PM to midnight.
There has been no sexual activity, so pregnancy is not a concern.
What could be the issue? I am worried about this situation as I will be traveling abroad on May 24th for over a month.

Hello, the factors that can affect the menstrual cycle or menstrual flow are numerous, including age, environment, lifestyle, stress, emotional instability, weight changes, medications, emergency contraception, diet, polycystic ovary syndrome, lesions of the uterus or cervix, infections, ovulation, pregnancy, and breastfeeding, among others.
If you need to delay your period, it is advisable to consult a gynecologist for examination and adjustment.
Thank you! Wishing you peace and health, Dr.
Zhang.

More Info


Irregular menstrual cycles can be concerning, especially when there are notable changes in flow, timing, and associated symptoms. Based on your description, it seems that you have a history of a relatively consistent menstrual pattern, with heavy flow for the first few days and some discomfort, which is common for many individuals. However, the recent irregularities you experienced in April, including a delayed period and unexpected changes in flow, warrant further exploration.

There are several potential causes for irregular menstrual cycles, and understanding these can help you identify whether you should seek medical advice. Here are some common factors that could contribute to the changes you are experiencing:
1. Hormonal Imbalances: The menstrual cycle is regulated by a complex interplay of hormones, including estrogen and progesterone. Fluctuations in these hormone levels can lead to irregularities in your cycle. Stress, significant weight changes, or underlying health conditions such as polycystic ovary syndrome (PCOS) can disrupt hormonal balance.

2. Stress and Lifestyle Factors: Psychological stress can significantly impact your menstrual cycle. Changes in your daily routine, sleep patterns, or emotional well-being can lead to variations in cycle timing and flow. It’s important to consider any recent life changes that may have contributed to increased stress.

3. Medical Conditions: Certain medical conditions can affect menstrual regularity. Conditions such as thyroid disorders, uterine fibroids, or endometriosis can lead to changes in menstrual patterns. If you have a family history of such conditions, it may be worth discussing with your healthcare provider.

4. Age and Perimenopause: If you are in your late 30s or early 40s, you may be approaching perimenopause, a transitional phase before menopause characterized by hormonal fluctuations and irregular cycles. This can lead to changes in flow, cycle length, and associated symptoms.

5. Medications: If you have recently started or stopped any medications, including hormonal contraceptives, this could also affect your menstrual cycle. Some medications can cause changes in bleeding patterns.

Given your upcoming travel plans, it is understandable that you are concerned about these changes. While some irregularities can be benign, it is essential to monitor your symptoms closely. If you experience any of the following, it would be advisable to consult a healthcare provider:
- Severe pain or discomfort that is not typical for you.

- Significant changes in the volume of bleeding, such as soaking through a pad or tampon every hour for several hours.

- Bleeding that lasts longer than a week.

- Any other unusual symptoms, such as fever, chills, or unusual discharge.

In the meantime, maintaining a healthy lifestyle, managing stress, and keeping track of your menstrual cycle can be beneficial. Consider using a menstrual tracking app to monitor your cycles, symptoms, and any changes you notice. This information can be helpful for your healthcare provider if you decide to seek further evaluation.

In conclusion, while irregular menstrual cycles can be concerning, they are not uncommon and can result from various factors. If your symptoms persist or worsen, seeking medical advice is the best course of action to ensure your health and well-being. Safe travels, and I hope you find relief and clarity regarding your menstrual health soon.
