Welcome to HCM,
As you have poly cystic ovarian disease
and hypothyrodism, both these conditions cause infertility.
You are on regular medication for hypothyrodism and is under control. so i advise you to consult your doctor and discuss about oral contraceptive
which has to be taken for three months which will help both in treating your irregular periods
and PCOD,and ovulation induction
drugs which will help to conceive.
