Irregular Menstrual Cycles After Birth Control Use - Obstetrics and Gynecology

A good friend has been coming for a long time without stopping?


Dear Dr.
Wang,
Thank you for your previous response.
Since I started taking birth control pills last month, my menstrual flow began on November 2nd and has increased since then.
Interestingly, the color is a murky brown and has an unpleasant odor.
A year or two ago, my periods were either absent or lasted for one to two months, and I had undergone examinations at a medical center.
Blood tests indicated that I have entered menopause.
The doctor prescribed hormones and progesterone for a period, but I stopped taking them for a while.
Before my period started on October 11th, I experienced headaches for over ten days, and medication did not help.
Is it possible that taking birth control pills is causing these issues? Today, I feel a lot of pressure in my chest, and could this be related to the increased menstrual flow?
Thank you for your guidance.
Wishing you happiness and health.
Best regards,
Lai

During menopause, irregular menstruation is common.
If a gynecologist examines and finds no abnormalities, hormone therapy can be used for adjustment; it may also help with headaches.

Dear 賴留,
Thank you for reaching out with your concerns regarding your menstrual cycle after starting birth control pills. It’s understandable to feel anxious about changes in your body, especially after experiencing irregular menstrual cycles in the past. Let’s break down your situation and address your questions.

Firstly, it’s important to recognize that hormonal contraceptives, such as birth control pills, can significantly affect your menstrual cycle. When you start taking these pills, your body undergoes hormonal changes that can lead to various side effects, including changes in the flow, color, and consistency of menstrual blood. The brown, coffee-colored discharge you’re experiencing is often old blood that takes longer to exit the uterus, which can be common when starting or adjusting to hormonal birth control.

The fact that you mentioned your menstrual cycle has been irregular in the past, along with your recent diagnosis of entering perimenopause, adds another layer of complexity. Perimenopause is the transitional phase leading up to menopause, during which hormonal fluctuations can cause irregular periods, changes in flow, and other symptoms such as headaches and mood swings. It’s not uncommon for women in this stage to experience a mix of symptoms, including heavy bleeding or spotting, which may be exacerbated by hormonal contraceptives.

Regarding your current symptoms of chest tightness and increased menstrual flow, it’s crucial to monitor these closely. While some discomfort can be attributed to hormonal changes, persistent or severe symptoms should not be overlooked. Chest tightness, especially if it’s new or worsening, warrants immediate medical attention to rule out any serious conditions.

You mentioned that you have been prescribed hormones and progesterone in the past. If you have stopped taking these medications, it’s possible that your body is still adjusting to the absence of those hormones, which could contribute to your irregular cycles and symptoms. It may be beneficial to discuss with your healthcare provider whether continuing or adjusting your hormonal treatment is appropriate for you, especially considering your recent experiences with birth control pills.

In summary, the irregularities you are experiencing could be a combination of starting birth control, your perimenopausal status, and possibly the effects of stopping other hormonal medications. It’s essential to keep an open line of communication with your healthcare provider, who can help you navigate these changes and determine the best course of action for your health.

If your symptoms persist or worsen, particularly the chest tightness, please seek medical attention promptly. Your health and well-being are paramount, and it’s always better to err on the side of caution.

Wishing you good health and peace of mind as you navigate these changes.

Best regards,
