Being pregnant with multiples means you will have two, three, or more babies at once. Twins are the most common set of multiples. Your multiples can be identical. This means the babies are conceived from the same egg. Identical babies look alike, are the same gender, and have matching DNA. Or your multiples can be fraternal. This means the babies are conceived in separate eggs at the same time. Fraternal babies may or may not look alike and can be different genders. If you have a multiple of three or more, you can have a mix of identical and fraternal babies.
Path to improved health
Pregnancies with multiples have become more common. There are three major factors that can increase your chance of multiples. The first is if it runs in your or your spouse’s family. The second is if you are over the age of 30. The third is if you get pregnant from fertility treatment. This includes medicine and/or procedures. In vitro fertilization (IVF) increases your risk the most. With IVF, multiple embryos are fertilized in a lab, then inserted into a woman’s uterus. A minor factor that can increase your risk of multiples is having a high body mass index (BMI). If you have given birth before, it also increases your risk of getting pregnant with multiples.
Your doctor can diagnose if you are pregnant with multiples. They can do this with an ultrasound. They also can listen to the fetal heartbeats. You or your doctor may notice early signs that could suggest multiples. These include:
- an increased hCG level (pregnancy hormone)
- quick weight gain
- heightened nausea, or morning sickness
- increased tiredness
- early fetal movement.
Things to consider
Most women who are pregnant with multiples have normal pregnancies and give birth to healthy babies. However, a woman who is pregnant with multiples is considered high-risk. There is increased strain on you and the babies. Certain health problems may occur. You have a higher chance of getting conditions such as gestational diabetes. Your babies are at a higher risk of being born prematurely and having low birth weights.
Throughout the pregnancy, you will require more frequent prenatal checkups and tests than with a typical pregnancy. You also should focus on a healthy lifestyle. Eat a balanced diet, and make sure you are exercising and getting plenty of rest.
