Pregnancy is an exciting and joyful time, and for some women, the news of carrying twins can be even more thrilling. However, not all women who are pregnant with twins experience the same symptoms, and some may not have any at all. Here are some signs that may indicate a twin pregnancy:
1. Elevated hCG levels: Human chorionic gonadotropin (hCG) is a hormone produced by the placenta after a fertilized egg has implanted in the uterus. Women carrying twins generally have higher levels of hCG, which can be detected in a blood or urine test.
2. Increased morning sickness: Women carrying twins may experience more severe morning sickness, which can last longer and be more intense than in a singleton pregnancy.
3. Rapid weight gain: Women carrying twins typically gain more weight early in pregnancy due to the increased demand on the body. They may also experience a more pronounced “baby bump” earlier in pregnancy than women carrying a singleton.
4. Larger uterus: A healthcare provider may be able to feel a larger uterus during an exam in women carrying twins.
5. Fetal movement: Women carrying twins may feel fetal movement earlier and more frequently than in a singleton pregnancy.
6. Abnormal AFP test results: An alpha-fetoprotein (AFP) test is a routine prenatal screening test that measures a protein produced by the fetus. Women carrying twins may have higher levels of AFP, which could indicate a twin pregnancy.
7. Twins detected during ultrasound: The most definitive way to confirm a twin pregnancy is through ultrasound imaging. Twins can be detected as early as six weeks gestation.
