What are the possible causes of dark brown bleeding and abdominal pain on day 27 of a cycle in a 24-year-old female with PCOS, thyroid dysfunction, and a two-year history of infertility who has been taking Duphaston (dydrogesterone, days 16?25) for five months, and how can these symptoms be managed?
The dark brown bleeding is simply older blood, which is very common. Since you recently finished your Duphaston (dydrogesterone), this could be the start of your period or, possibly, implantation bleeding, given your journey with infertility. Your PCOS and thyroid levels can also influence your cycle. For management, I recommend taking a home pregnancy test in a few days. For the discomfort, a warm compress and rest can help. Please reach out to your specialist to discuss these symptoms; they can safely guide your next steps and check your hormone levels.
