If you are pregnant with more than one fetus, you can expect to have the same symptoms as those of a pregnancy with one fetus (called a singleton pregnancy). But the symptoms may happen earlier and may be worse. A multiple pregnancy is likely to cause:
- Early and excessive nausea and vomiting in the first trimester.
- Extra weight gain.
- A uterus that is larger than expected for your due date.
- More fetal movement than expected during the second trimester and later.
Later in the pregnancy, you are more likely to have:
- Varicose veins.
- Increasing backache.
- Trouble breathing (caused by pressure on the lungs from the uterus pushing up on the diaphragm).
- Indigestion (caused by pressure on the stomach from the large uterus).
- A very large belly
- Gestational diabetes.
- Preeclampsia, a serious disorder of circulation and blood pressure that affects both mother and fetuses.
- Preterm labor.
