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
Excessive weight gain, especially in early pregnancy
Fetal movements felt in different parts of the stomach at the same time
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.
