After a normal pregnancy I suffered two miscarriages in a row. What can I do to insure a normal pregnancy the next time?

Get a checkup. Most likely your next pregnancy will be normal and healthy. However, after 2 miscarriages in a row, an evaluation by your gynecologist or a reproductive endocrinologist is a good idea. Most problems that are found during an evaluation for recurrent miscarriage can be fixed: low thyroid, uterine scarring, are 2 examples of common curable problems in this situation. See your doctor! good luck!
