Prepare Your Health History
At your very first prenatal exam, your doctor may throw a million questions your way, about your health, your partner’s and your family’s history of things like genetic disorders and diseases (or you may get a talk from a genetic counselor). And it’s pretty common find yourself going, “Uh… I don’t know… maybe?” But this is serious stuff. Knowing about a genetic problem or pregnancy health condition that runs in your family can inform you and your doctor that you might need to be monitored extra closely, or it might make you decide to get special genetic testing to ensure baby’s doing okay. So it’s a good idea to get prepared. Here’s how.
Ask Your Parents Probing Questions
The number one thing your doctor will likely ask is your health history and age, since the chance of certain genetic issues (like Down syndrome) increases with maternal age. The second? Your family’s health history. “I ask about the patient’s mother’s pregnancies, if she had problems or if she had any babies with congenital malformations,” says Laura Riley, MD, ob-gyn and medical director of Labor and Delivery at Massachusetts General Hospital “Then, I move on to the other sides of the families.” And while you may think you know your family well, you may not realize that your mom had preeclampsia, or your partner may have heard there was a baby with health problems in his family but may not have ever asked for the details. Now’s the time to ask. “Sometimes it’s real obvious stuff,” says Dr. Riley. “But there are some things that aren’t that obvious, like if there are males in your family with mental retardation that’s unexplained. It could be Fragile X.”
Know What’s Not Important
“Most people give us their family’s medical history, like if a grandparent has a heart condition,” says Dr. Riley. “That’s important in general but not as important as fetal issues and maternal issues.” So think about whether any babies in your family were born prematurely or had birth defects, or if anyone has had genetic conditions like cystic fibrosis, Tay-Sachs disease or sickle cell anemia. But don’t be freaked out that you’re bringing up the wrong thing. “It’s okay to mention everything you think of,” says Dr. Riley. “Sometimes talking about one thing will bring up another that’s really important.”
The doctor will likely ask about your ethnic background as well, since certain conditions run in specific cultural lineages.
As for medical history, prenatal conditions that run in your family, like preeclampsia, gestational diabetes, hypertension and preterm labor are definitely important to bring up. But surprisingly, miscarriage is not. “Miscarriage is actually very common and vast majority are them are because of chromosomal problems that are a one-time thing, so I usually don’t make a big deal about that,” says Dr. Riley.
Make Your Partner Come Along
It’s okay to go to other prenatal appointments solo, but this is one your partner should definitely come along to. That’s because, while your family history is what affects your health, his family’s can affect baby’s. And even if you talk it over in advance, you might not be able to predict all the doc’s questions prior to the visit.
Know this: If either you or your man were adopted, or your used donor egg or sperm, you’ll have to accept that you may not have all the information other couples do in this case. That’s okay though. Share what you know with the doctor and listen carefully to make the best informed decisions you can.
Talk Over Some Serious Scenarios
While you’re discussing your own health, so your doc can watch you closely throughout pregnancy, you’re discussing baby’s health to figure out whether you should do genetic testing to see what baby’s risk of having genetic problems could be. But if baby has a birth defect or genetic disorder, know that it can’t be “healed.” Some parents-to-be choose to test because they want peace of mind that baby’s healthy. Others want to have advanced warning of certain issues so medical specialists can be there at birth. Still others might want to end the pregnancy, depending on baby’s risk factor. “It’s worth talking with your partner about what you’re going to do with the information,” says Dr. Riley. “Would you want to do the genetic testing and why do you want the results?” It’s not that you two have to know all the answers before the visit. Just have a general discussion about how you expect things to go. Your doctor or specialist can walk you through the decisions you’ll later make.
Consider a Genetic Counselor
Armed with your health histories, your doctor can explain the different genetic tests available to you and your partner. And together, you’ll make a decision about what tests you might want to get.
If your doctor doesn’t take an extensive family history, or doesn’t do genetic counseling, you may want to find someone else to talk you through the process. Usually, your hospital has a staff that can do this. If not, check out the American Congress of Medical Genetics website, where you can search for a counselor near you.
