The following are the most common symptoms of multiple pregnancy. However, each woman may experience symptoms differently. Symptoms of multiple pregnancy may include:
- Uterus is larger than expected for the dates in pregnancy
- Increased morning sickness
- Increased appetite
- Excessive weight gain, especially in early pregnancy
- Fetal movements felt in different parts of the stomach at the same time
How is multiple pregnancy diagnosed?
Many women suspect they are pregnant with more than 1 baby. Diagnosis of multiple fetuses may be made early in pregnancy. This is especially true if fertility treatments were used. In addition to a complete medical history and physical examination, diagnosis may be made by:
- Pregnancy blood testing. Levels of human chorionic gonadotropin (hCG) may be quite high with multiple pregnancy.
- Alpha-fetoprotein. Levels of a protein released by the fetal liver and found in the mother's blood may be high when more than 1 fetus is making the protein.
- Ultrasound. A diagnostic imaging method that uses high-frequency sound waves to create images of blood vessels, tissues, and organs. Ultrasounds can be done with a vaginal transducer, especially in early pregnancy. Or with an abdominal transducer in later pregnancy.
