Multiple miscarriages can be devastating, but the best thing you can do is to enlist the help of a reproductive endocrinologist or a doctor who specializes in high-risk pregnancies to try to determine why you lost those previous pregnancies. Early pregnancy losses tend to be caused by genetic issues, meaning the embryo's genes were unhealthy and unable to continue growing into a healthy baby, while
losses in the second or third trimester are often due to obstetrical complications such as placental abruption (in which the placenta separates from the uterus), an infection, high blood pressure, or a variety of other medical problems.
To get to the bottom of your problem, your fertility specialist will most likely want to rule out hormonal conditions like thyroid disease, adrenal gland disease, and diabetes, which can cause multiple miscarriages, as well as other chronic diseases of the heart, liver, and kidneys. He or she will also check for problems with the uterus that could impact pregnancy loss. Your husband should undergo a semen analysis as well, to see if sperm abnormalities could be causing the repeated miscarriages.
If the causes of your miscarriages can be identified, there may be a variety of treatments available to help you carry a baby to term. Your doctor will also probably suggest you maintain a healthy weight -- it'll make getting pregnant and having a healthy pregnancy easier -- so you should ask about how to begin a nutritious diet and fitness routine now.
