The duration of the menstrual cycle has increased?

It has been a week since I started taking the contraceptive pill (Huishe - Xindingou) on the first day of my menstrual cycle, and my flow is still quite heavy.
Previously, my menstrual cycle would completely end within a week without taking the pill.
Is this normal?

More Info

Prolonged menstrual flow after starting birth control can be a common experience for many women, especially when beginning a new contraceptive method. Birth control pills, such as the one you mentioned (likely a combination pill), can cause various changes in your menstrual cycle as your body adjusts to the hormones.
When you start taking birth control pills, your body undergoes hormonal changes that can affect your menstrual cycle. It is not unusual for women to experience irregular bleeding or prolonged periods during the first few months of starting the pill. This is often referred to as "breakthrough bleeding" and can occur as your body adapts to the new hormone levels.
Typically, the first few months on birth control pills can lead to changes in the menstrual cycle, including:
1. Prolonged Bleeding: Some women may experience longer periods or heavier bleeding initially. This can be due to the body adjusting to the synthetic hormones in the pill.

2. Irregular Cycles: It's common to have irregular periods during the first few months. Some women may have shorter cycles, while others may have longer cycles or skip periods altogether.

3. Spotting: Light spotting between periods is also a common side effect when starting birth control pills.

4. Changes in Flow: The flow may be heavier or lighter than what you experienced before starting the pill.

While these changes are often normal, it is essential to monitor your symptoms. If you find that your menstrual flow remains heavy or prolonged beyond the initial adjustment period (usually the first three months), or if you experience severe pain, it is advisable to consult with your healthcare provider. They may want to rule out other potential causes of heavy bleeding, such as fibroids, polyps, or hormonal imbalances.

In some cases, if the bleeding is excessive or bothersome, your doctor may suggest trying a different formulation of birth control or exploring other options that may better suit your body's needs.
Additionally, if you have any concerns about your health or if you experience symptoms such as dizziness, fatigue, or significant pain, it is crucial to seek medical attention promptly. Your healthcare provider can provide personalized advice and may recommend further evaluation or treatment options based on your specific situation.

In summary, while prolonged menstrual flow after starting birth control can be normal, it is essential to pay attention to your body and consult with your healthcare provider if you have any concerns or if the symptoms persist. They can help ensure that you find the right contraceptive method that works for you and your health.
