Do I have an increased chance of having a miscarriage with PCOS?
It is unclear what the relationship is between PCOS and miscarriagerisk. However, many physicians and researchers believe that the risk for pregnancy loss is higher.
Can I do anything to prevent a miscarriage?
Most likely, no. If the loss is due to a genetic abnormality, once the pregnancy has been established, nothing can be done to prevent a miscarriage. Sometimes a physician will place a patient who has a threatened pregnancy loss on bed rest or pelvic rest. While it is not clear if this can actually prevent a miscarriage, it is still best to follow your doctor’s advice.
Is taking the metformin while pregnant dangerous?
While of course it is always best to follow your physician’s orders, it is generally thought that maintaining your metformin regimen may reduce your miscarriage risk. When pregnant, you should have a discussion regarding the pros and cons of continuing your medication.
If I have a miscarriage, can I still have a healthy pregnancy later?
Absolutely. Many women with recurrent miscarriages go on to have normal, healthy pregnancies.
