Abnormal bleeding phenomenon


I started using Qlaira in April, and this month, when I had only 10 pills left, I experienced brown discharge every day.
I visited a gynecologist, and the doctor said they had never encountered this situation before.
I had a pelvic exam (the doctor said everything looked fine), and I was given medication and injections, but the discharge continued.
Later, I went to another doctor who performed an ultrasound and said everything was normal, indicating that it should not be related to Qlaira.
They prescribed a three-day course of hormones and progesterone, but I only took it for one day and then stopped.
Can you tell me what might be causing this bleeding?

Hello Ms.
Chen: Experiencing vaginal bleeding before finishing your birth control pills is not uncommon, especially during the first or second pack.
Doctors often prescribe low-dose hormones and progestins to help stop the bleeding.
However, it may take two to three days for the bleeding to subside, and stopping the medication after just one day may lead to continued bleeding.

The reasons for bleeding before completing the birth control pack are often due to missed doses or the concurrent use of other medications.
It could also be influenced by certain foods affecting the gastrointestinal absorption of the medication, or it may be related to the dosage of the birth control pills themselves.

If you are only experiencing a small amount of brown discharge, it is advisable to continue taking the pills until the last one.
After that, you can start the next pack to see if the same issue occurs.
Generally, any bleeding tends to improve when taking the second or third pack.
If there is no improvement, you may consider switching to a different type of birth control pill.

More Info


Abnormal bleeding while on birth control can be a concerning issue for many women. It is important to understand that various factors can contribute to this phenomenon, especially when using hormonal contraceptives like the IUD (Intrauterine Device) known as Mirena (祈麗安).
Firstly, it is essential to recognize that hormonal contraceptives work by altering the hormonal balance in the body to prevent ovulation and regulate menstrual cycles. However, these changes can sometimes lead to side effects, including irregular bleeding or spotting, especially during the initial months of use. This is often referred to as "breakthrough bleeding." It is not uncommon for women to experience this, particularly in the first few months after starting a new birth control method.
In your case, experiencing brown discharge daily while on Mirena could be attributed to several factors:
1. Hormonal Adjustment: When starting a new hormonal contraceptive, your body may take time to adjust to the new hormone levels. This adjustment period can lead to irregular bleeding or spotting, which may manifest as brown discharge. Brown discharge typically indicates older blood that has taken longer to exit the body.

2. IUD Placement: If the IUD is not positioned correctly, it can cause irritation to the uterine lining, leading to abnormal bleeding. Although your doctor performed an internal examination and stated that everything seemed fine, it might be worth discussing the possibility of the IUD's placement again, especially if the bleeding persists.

3. Underlying Conditions: While hormonal contraceptives can cause breakthrough bleeding, it is also essential to rule out other underlying conditions that could contribute to abnormal bleeding. These may include uterine fibroids, polyps, or endometriosis. Since you mentioned that you had an ultrasound and it showed no issues, this is a positive sign, but if the bleeding continues, further investigation may be warranted.

4. Medication Compliance: You mentioned that you stopped taking the prescribed hormones and progesterone after just one day. It is crucial to follow your healthcare provider's recommendations regarding medication, as stopping treatment prematurely can lead to ongoing irregularities in your cycle. Hormonal treatments are often designed to stabilize your cycle, and discontinuing them can result in a return of abnormal bleeding.

5. Stress and Lifestyle Factors: Stress, changes in weight, and lifestyle factors can also impact your menstrual cycle. If you have experienced significant stress or changes in your routine, this could contribute to your symptoms.
In conclusion, while it is common to experience some irregular bleeding when starting a new birth control method, persistent or concerning symptoms should not be ignored. It is advisable to maintain open communication with your healthcare provider about your symptoms. If the brown discharge continues or worsens, consider scheduling a follow-up appointment to discuss further evaluation or alternative contraceptive options. Your health and comfort are paramount, and there are various solutions available to help manage your symptoms effectively.
