Bleeding after taking Yuzi for 20 days?


Hello, doctor.
I started taking Yaz about 10 days after the first day of my last menstrual period and had sexual intercourse 2 to 4 times with ejaculation inside.
Recently, I noticed some slight bleeding from my genital area, along with symptoms like drowsiness, increased hunger, and bloating.
Should I see a doctor, or are these symptoms considered normal? Thank you, doctor.

More Info


Light bleeding after starting a new birth control method, such as the pill, can be a common occurrence, especially in the first few months of use. This phenomenon is often referred to as "breakthrough bleeding." It can happen as your body adjusts to the hormones in the birth control pill. However, it is essential to consider various factors before deciding whether to see a doctor.

1. Understanding Breakthrough Bleeding: When you start taking birth control pills, your body may take some time to adjust to the new hormone levels. Breakthrough bleeding can occur, particularly during the first few months, and is usually not a cause for concern. It is often light and may be accompanied by other symptoms like mood swings or mild cramping. If the bleeding is light and not accompanied by severe pain or other alarming symptoms, it may be a normal adjustment.

2. Other Symptoms: You mentioned experiencing symptoms such as increased sleepiness, hunger, and bloating. These can also be side effects of hormonal birth control. However, if these symptoms are severe or worsening, it may warrant a consultation with a healthcare provider. It’s essential to differentiate between normal side effects and symptoms that could indicate a more serious issue, such as an infection or an adverse reaction to the medication.

3. Potential Pregnancy: Given that you mentioned having unprotected intercourse with ejaculation, there is a possibility of pregnancy, even while on birth control. If the bleeding is unusual for you or if you experience other signs of pregnancy (such as missed periods, nausea, or breast tenderness), it would be prudent to take a pregnancy test. If the test is positive or if you have concerns about the possibility of pregnancy, you should see a doctor.

4. When to Seek Medical Attention: You should consider seeing a doctor if:
- The bleeding becomes heavy or is accompanied by severe pain.

- You experience symptoms that are unusual for you, such as significant changes in mood, severe headaches, or visual disturbances.

- You have concerns about the effectiveness of your birth control method or if you suspect you might be pregnant.

5. Consulting Your Healthcare Provider: If the bleeding persists or if you are uncomfortable with the symptoms you are experiencing, it is always a good idea to consult your healthcare provider. They can provide personalized advice based on your medical history and current situation. They may also suggest alternative birth control methods if the side effects are bothersome.

In summary, light bleeding after starting birth control can be normal, especially in the initial months. However, it is essential to monitor your symptoms and consult a healthcare provider if you have any concerns or if your symptoms change significantly. Your health and peace of mind are paramount, so don’t hesitate to seek professional advice when in doubt.
