Hi,
Welcome to ehealthforum,
If you had been diagnosed to have PCOS, you should consider continuing the insulin modifiers which help to reverse PCOS changes and return ovarian function and ovulation. If you suspect being pregnant (occasional ovulation is possible even when having PCOS), consider visiting your doctor/gynecologist at the earliest for thorough examination (to confirm pregnancy related changes/signs in body) and blood/serum HCG level test (to confirm/rule out pregnancy accurately). If pregnancy gets ruled out, consider going ahead with further evaluation to look for the current status of the problem and underlying cause for the missed periods. Treatment as required (based on examination and investigations results) would be started to help you regulate your periods. Consider getting restarted on insulin modifiers for better control of PCOS. Once PCOS is under control, ovulation inducers can be started to help you with ovulation and increase your chances of pregnancy. If you are trying for pregnancy, monitor cervical mucus changes and the BBT (basal body temperature) charting to predict your ovulation (along with the follicular study) and time your intercourse for having fruitful results. Have intercourse in positions that allow for deeper penetration for high deposit of semen. Have diet with foods rich in zinc content to ensure better maturation of egg and sperms. Continue with the treatment prescribed and be in regular monitoring and follow-up with your treating doctor/gynecologist and report any new/abnormal symptoms immediately. Drink plenty of water. Take adequate rest.
Take care.
