Hello: Based on your description, it may be a case of ovulatory bleeding.
You could track your basal body temperature over time to see at which phase of your menstrual cycle the bleeding occurs, whether you have a regular menstrual cycle, or if you are experiencing anovulatory cycles or menstrual irregularities.
Thank you for your message!

Irregular menstrual cycles can be a source of concern for many young women, and your experience of having periods twice in a month for several years is certainly something that warrants attention. There are multiple factors that can contribute to irregular periods, and understanding these can help you and your healthcare provider determine the best course of action.

Firstly, hormonal imbalances are one of the most common causes of irregular periods. The menstrual cycle is regulated by a complex interplay of hormones, including estrogen and progesterone. If there is an imbalance in these hormones, it can lead to irregularities in your cycle. Conditions such as polycystic ovary syndrome (PCOS) are known to cause hormonal imbalances and can lead to irregular periods, weight gain, and other symptoms.

Another factor to consider is stress. High levels of stress can affect your body in various ways, including disrupting your menstrual cycle. Stress can lead to changes in hormone levels, which may result in missed periods or irregular cycles. Lifestyle factors such as diet, exercise, and sleep patterns can also play a significant role in menstrual regularity. For instance, excessive exercise or significant weight loss can lead to hormonal changes that affect your cycle.

Additionally, underlying medical conditions such as thyroid disorders or uterine abnormalities can also cause irregular periods. Thyroid hormones play a crucial role in regulating the menstrual cycle, and any dysfunction in the thyroid gland can lead to irregularities. Similarly, conditions like fibroids or polyps in the uterus can disrupt normal menstrual flow.

Given that you have been prescribed medication to help regulate your cycle, it is important to discuss your concerns with your healthcare provider. They may suggest further testing to rule out any underlying conditions that could be contributing to your irregular periods. This could include blood tests to check hormone levels, imaging studies to examine the ovaries and uterus, or even a referral to a specialist if necessary.

In terms of managing your symptoms, it is essential to maintain a healthy lifestyle. This includes eating a balanced diet, managing stress through relaxation techniques or exercise, and ensuring you get adequate sleep. Regular check-ups with your healthcare provider can also help monitor your condition and adjust treatment as needed.

If you find that the medication you are taking is not providing the desired results or if you have concerns about the frequency of use, it is crucial to communicate this with your doctor. They may explore alternative treatments or lifestyle modifications that could help regulate your menstrual cycle without the need for frequent medication.

In summary, irregular periods can stem from a variety of causes, including hormonal imbalances, stress, lifestyle factors, and underlying medical conditions. It is important to work closely with your healthcare provider to identify the root cause of your irregular cycles and develop an appropriate treatment plan. Regular monitoring and open communication about your symptoms and concerns will be key in managing your menstrual health effectively.
