I was 6 week pregnant when my doctor told that my embryo did not have heartbeat. could it be a high dose of dostinex (if i haven't high prolactin)?

Not sure: Ther are conflicting data on dostinex:available data indicates a somewhat increased rate of congenital abnormalities in patients who became pregnant while treated but one study concluded that "fetal exposure through early pregnancy does not induce any increase in the risk of miscarriage or fetal malformation." However,at 6 weeks is when the heart beat is first heard so could dates be off?????
