Antibiotics can indeed have an impact on menstrual cycles, although the relationship is complex and not fully understood. In your case, the prolonged menstrual period and the changes in flow and color could potentially be influenced by the antibiotics you were prescribed. However, it is essential to consider other factors that might contribute to these changes as well.

Firstly, antibiotics can disrupt the balance of gut microbiota, which in turn can affect hormonal regulation. The gut microbiome plays a significant role in the metabolism of hormones, including estrogen and progesterone, which are crucial for regulating the menstrual cycle. An imbalance in gut bacteria due to antibiotic use may lead to hormonal fluctuations, potentially resulting in changes to your menstrual cycle.

Secondly, stress and lifestyle changes can also affect your menstrual cycle. If you have been experiencing stress, whether from health issues or other life events, this could contribute to irregularities in your period. Additionally, changes in diet, exercise, or sleep patterns can also play a role.

Regarding your specific symptoms, the heavy bleeding with clots and the subsequent changes in flow could indicate a few possibilities. Heavy menstrual bleeding, known as menorrhagia, can be caused by hormonal imbalances, uterine fibroids, polyps, or other underlying conditions. The fact that you experienced a significant change in your skin condition (acne) could also suggest hormonal fluctuations, which might be exacerbated by the antibiotics.

Given that your menstrual period has been prolonged and is accompanied by other symptoms, it would be prudent to consult a healthcare professional. In this case, you should consider seeing a gynecologist, as they specialize in female reproductive health and can provide a thorough evaluation of your menstrual irregularities. They may perform a physical examination, take a detailed medical history, and possibly order tests such as blood work or imaging studies to determine the underlying cause of your symptoms.

If the gynecologist suspects that there may be an endocrine issue, they might refer you to an endocrinologist for further evaluation. However, starting with a gynecologist is typically the best approach for menstrual irregularities.

In summary, while antibiotics can potentially affect menstrual cycles, it is essential to consider other factors that may be contributing to your symptoms. Given the changes you've experienced, it would be wise to seek medical advice to rule out any underlying conditions and to receive appropriate care. Monitoring your symptoms and keeping track of any additional changes will also be helpful information to share with your healthcare provider.
