Hi,
Welcome to ehealthforum,
If the uterine septum (if diagnosed) has been removed, chances of pregnancy should improve. If you have been diagnosed with PCOS, then treatment with insulin modifiers would help to reverse the changes (most common cause for PCOS is insulin resistance, hence use of these helps in control of PCOS better). Once PCOS is under control, ovulation inducers can be started to help you with ovulation and increase your chances of pregnancy. If 3 cycles with ovulation inducers do not work, combination of HCG trigger injections can be tried. If these fail, assisted reproductive techniques like IVF or ICSI should be considered. 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.
