Hello, 
PCOD is definitely a vary tricky problem but a patient approach definitely bears fruit to the patient. 
The most important treatment apart from ovulation induction medicine is,shedding your weight and being in your normal BMI range and other treatment is to take care of your insulin resistance by taking regular METFORMIN under the guidance of your doctor. 
It is said that even a 10% reduction in weight regains the fertility of the patient.
Your doctor is giving you the right treatment.Just follow the treatment and trust your doctor. 
However I feel the dose of METFORMIN should be 500 mg twice a day and not 250 mg only.
You shall definitely get pregnant,although timing can't be predicted.
Best of luck 
Thanks 

hi there,

nice to meet you here in HCMagic

While it is possible to become pregnant, women with PCOS tend to suffer a much higher rate of miscarriages. Estimates put the rate of miscarriages in women with PCOS at 45% although some believe the figure may be higher. However, experts aren’t sure why exactly this is.

Fertility problems experienced by women with PCOS may be related to the elevated hormone, insulin, or glucose levels, all of which can interfere with implantation as well as development of the embryo. Additionally, abnormal insulin levels may also contribute to poor egg quality, making conception more difficult.

Stabilizing hormone levels can help fertility by promoting ovulation. Some doctors may also prescribe ovulation medications, such as Clomid, to encourage ovulation. If you are thinking of conceiving, be sure to discuss the issue with your doctor. Not all of the medications used to help PCOS sufferers are safe to use during pregnancy and may need to be discontinued.

Although getting pregnant can be problematic for women with PCOS, many have found it easier to get pregnant the second time around. Additionally, some women have found that their menstrual cycles regulate themselves after a pregnancy. Following a healthy diet and exercising regularly will also help to promote fertility.
hope i helped with your query,

Hi,
PCOD is the most common hormonal disorder observed in women of reproductive age and also the best treatable condition in view of the several treatment modalities and also the good response observed in so many cases. You are on to a good line of treatment and do not worry, chances of conception are good with a 30-40% success rate with Clomiphene alone in a 6-month period. Try to reduce your weight further to reach a BMI of 19-25. Have patience and strictly adhere to the treatment regimen your doctor as advised you. Good luck.
