1st Trimester: 1st Prenatal Visit

It's the first doctor visit of your twin pregnancy, congratulations! Twins can be diagnosed as early as 6 weeks, so you've learned about your double surprise early. During this visit, your doctor will check your overall health and determine your due date. He or she will also look for risk factors that might affect your health or your babies' health based on your medical history, family history, and age. Your doctor will answer any questions you have about pregnancy. He or she will explain that having twins puts you at a higher risk for pregnancy complications such as preeclampsia and preterm delivery. There's a lot to cover, so this will probably be the longest of all of your prenatal visits.

What You Can Expect:

Be Prepared to Discuss:

It's important to be as open as possible with your doctor during your pregnancy so that your doctor can help both you and your babies be safe and healthy. Be prepared to openly talk about:

  • Your personal and family medical history, including any chronic health problems
  • Your ethnic background; some groups are more likely to pass on genetic disorders like cystic fibrosis
  • Your lifestyle habits that could affect your babies, such as alcohol use, smoking, or illicit drug use
  • Any incidence or history of domestic violence
  • Your current emotional state and any history of depression or mental illness
  • Diet, exercise, and optimal weight gain during pregnancy
