Persistent Light Bleeding After Starting Second Pack of Birth Control Pills - Obstetrics and Gynecology

Continuing to experience light bleeding while taking the second pack of Yaz?


On August 3rd, I took the first pack of Yaz and experienced no bleeding.
On August 27th, my period started, and I immediately began the second pack, taking the first pill.
Since then, up until today, September 17th, I have had light bleeding, sometimes bright red and sometimes dark red, resembling small spots, and occasionally watery discharge.
Additionally, there is no other discharge, but I have noticed an unusual odor in the vaginal area (which I did not have before).
I also feel itchy in that area every day.
Upon examining with a mirror, I noticed that the inner side of my labia seems a bit raw (I'm not sure if it looked like this before).
I understand that starting low-dose contraceptive pills can cause bleeding.
I currently have three active pills left.
Should I continue taking them, or should I temporarily stop and schedule an appointment with a gynecologist? Thank you.

More Info


Persistent light bleeding after starting a new pack of birth control pills can be concerning, especially when accompanied by other symptoms such as itching, unusual odor, and changes in the appearance of the vulva. Here’s a comprehensive overview of what might be happening and what steps to take.


Understanding Breakthrough Bleeding
When starting a new pack of birth control pills, especially if they are low-dose, some women may experience what is known as "breakthrough bleeding." This is a common side effect, particularly during the first few months of use, as the body adjusts to the hormonal changes. Breakthrough bleeding can manifest as light spotting or bleeding that occurs between periods. It is usually not a cause for alarm, but it can be bothersome.


Possible Causes of Your Symptoms
1. Hormonal Adjustment: As mentioned, your body may still be adjusting to the hormones in the birth control pills. This adjustment period can lead to irregular bleeding patterns.

2. Infection: The presence of an unusual odor and itching could indicate a vaginal infection, such as bacterial vaginosis or a yeast infection. These infections can sometimes cause irritation and lead to bleeding.

3. Allergic Reaction or Irritation: If you have noticed changes in the appearance of your vulva, such as broken skin, it could be due to irritation from soaps, hygiene products, or even the birth control pills themselves.
4. Other Medical Conditions: Conditions such as polyps or fibroids can also cause abnormal bleeding. While less common, it’s important to consider these possibilities if symptoms persist.


Recommendations
Given your symptoms, here are some steps you should consider:
1. Continue Taking the Pills: If you are not experiencing severe pain or heavy bleeding, it is generally advisable to continue taking the pills until you can consult with a healthcare provider. Stopping the pills abruptly can lead to further hormonal fluctuations.

2. Monitor Symptoms: Keep track of your bleeding patterns, any changes in odor, and any other symptoms such as itching or pain. This information will be helpful for your healthcare provider.

3. Consult a Healthcare Provider: It is important to schedule an appointment with a gynecologist as soon as possible. They can perform a thorough examination, possibly including a pelvic exam and tests to rule out infections or other underlying conditions.

4. Avoid Self-Diagnosis: While it’s tempting to look up symptoms online, self-diagnosing can lead to unnecessary anxiety. A healthcare provider can give you a proper diagnosis and treatment plan.

5. Maintain Good Hygiene: In the meantime, ensure that you are practicing good hygiene. Avoid using scented products in the genital area, and wear breathable cotton underwear to reduce irritation.


Conclusion
While breakthrough bleeding can be a normal side effect of starting birth control pills, the presence of an unusual odor, itching, and changes in the vulva are concerning and warrant a medical evaluation. It’s essential to consult with a healthcare provider to rule out infections or other conditions that may require treatment. Your health and comfort are paramount, and addressing these symptoms promptly will help ensure your well-being.
