Understanding post-pill bleeding can be a complex issue, especially for women who have recently altered their hormonal balance through medications like birth control pills. In your case, it seems that you have experienced a significant change in your menstrual cycle, which has raised concerns about the nature of your bleeding.

Firstly, it's important to understand that hormonal contraceptives, such as birth control pills, can lead to various changes in menstrual patterns. When you take the pill, it works by regulating hormones that control the menstrual cycle. If you suddenly stop taking the pill or miss doses, your body may react by causing irregular bleeding, often referred to as "withdrawal bleeding." This can manifest as light spotting or more significant bleeding, depending on how your body is adjusting to the hormonal changes.

In your situation, you mentioned that your menstrual duration increased from 8 days to 13 days after the diagnosis of uterine polyps. Uterine polyps can contribute to abnormal bleeding patterns, including prolonged menstrual bleeding, spotting between periods, or heavier menstrual flow. The presence of polyps can disrupt the normal shedding of the uterine lining, leading to irregularities in your cycle.

The bleeding you experienced starting on August 17 could be attributed to several factors:
1. Withdrawal Bleeding: If you stopped taking the pill, your body might be experiencing withdrawal bleeding, which can occur as your hormone levels drop. This type of bleeding can be unpredictable and may not follow the typical menstrual cycle pattern.

2. Hormonal Fluctuations: After stopping the pill, your body may take some time to readjust its hormonal levels. This adjustment period can lead to irregular bleeding or spotting.

3. Impact of Uterine Polyps: The polyps themselves can cause abnormal bleeding. If they are present, they may contribute to the bleeding you are experiencing, regardless of your use of hormonal contraceptives.

4. Effect of Medications: The hemostatic medications prescribed by your doctor are intended to help control bleeding. However, if the underlying cause of the bleeding (such as polyps) is not addressed, the bleeding may persist despite treatment.

Given that you experienced bleeding after stopping the pill and have a history of uterine polyps, it is crucial to monitor your symptoms closely. If the bleeding continues or worsens, or if you experience other concerning symptoms such as severe pain, dizziness, or fatigue, it is essential to seek medical attention promptly.

In terms of management, your healthcare provider may recommend further evaluation, such as a pelvic ultrasound or hysteroscopy, to assess the status of the polyps and determine if they require treatment. Treatment options for uterine polyps can include medication or surgical removal, depending on their size and symptoms.

In conclusion, post-pill bleeding can be influenced by various factors, including hormonal changes, the presence of uterine polyps, and the effects of medications. It is essential to maintain open communication with your healthcare provider and follow their recommendations for monitoring and treatment. Keeping a detailed record of your bleeding patterns, including the duration and characteristics of the bleeding, can also be helpful for your healthcare provider in determining the best course of action.
