hi,
Thank you for the question.Both the medications you are using are useful in PCOD.
Metformin helps you in conception and helps in treating PCOD.
Folic acid is important to prevent certain developmental abnormalities in fetus(in case you conceive).You can continue both of them as they are safe.But apart from these you may also need some
ovulation induction drugs(such as
clomiphene) and follicular scans in the middle of menstrual cycle.These will help you to know if you are ovulating properly and chances of conception increase.Discuss with your gynaecologist and to include these in your treatment. All the best.
