[/INST] Hi,I understand your concerns but it seems that you are experiencing hormonal imbalance. I recommend that you undergo a hormonal profile blood test including TSH, T3, T4, estrogen, progesterone, prolactin  and LH. Treatment will be according to the test results.Hope I have answered your query. Let me know if I can assist you further. Regards,Dr. Salah Saad Shoman </s>
