Years ago, most twins came as a surprise. Now, thanks to advances in prenatal care, most women learn about a multiple pregnancy early. You might suspect you are pregnant with multiples if you have more severe body changes, including: 
•    Rapid weight gain in the first trimester 
•    Intense nausea and vomiting 
•    Extreme breast tenderness 
Your doctor can confirm whether you are carrying more than one baby through ultrasound. If you are pregnant with twins or other multiples, you will need to see your doctor more often than women who are carrying only one baby because your risk of complications is greater. Women carrying more than one baby are at higher risk of: 
•    Preterm birth 
•    Low birth weight 
•    Preeclampsia 
•    Gestational diabetes 
•    Cesarean birth 
More frequent prenatal visits help your doctor to monitor your and your babies' health. Your doctor will also tell you how much weight to gain, if you need to take extra vitamins, and how much activity is safe. With close monitoring, your babies will have the best chance of being born near term and at a healthy weight. 
After delivery and once your babies come home, you may feel overwhelmed and exhausted. Ask for help from your partner, family, and friends. Volunteer help and support groups for parents of multiples also can ease the transition.
