What to Know if You're Pregnant with Multiples

by Allison Bush Editor

Morning sickness times two

Morning sickness is caused by high levels of the hormone human chorionic gonadotropin, and because levels of this hormone are higher in twin pregnancies, women may experience a higher incidence of nausea and vomiting in the first trimester.

You may need more folic acid

Women who are pregnant with twins or more should take 1000 mcg a day. Folic acid is known to reduce risk of neural tube birth defects such as spina bifida.

Your risk of gestational diabetes is higher

Gestational diabetes is a temporary form (in most cases) of diabetes in which the body does not produce adequate amounts of insulin to deal with sugar during pregnancy. A study from 2009 concluded that women between the ages of 25 and 30 years and African-American women had the highest risk of developing gestational diabetes in twin pregnancies

You may deliver earlier

Twins are at a higher risk of a preterm delivery; almost 60% of twins are delivered preterm, while 90% of triplets are preterm.. Many moms who are carrying twins go into labor at around 36 or 37 weeks instead of the normal 39 or 40 weeks for single pregnancies. Generally, if twins make it past the 34 week mark, complications should be minimal.

You may have to have a Cesarean section delivery

The chances of having a C-section are definitely higher if you're pregnant with twins, however, twins may be delivered vaginally depending on their positions, estimated weights and gestational age. Multiples of three or more are less likely to be delivered vaginally.

Your chance of conceiving twins increases with age

As you age, your chance of conceiving twins increases. Researchers have found that women over 35 produce more follicle stimulating hormone (FSH) than younger women, which may cause more than one egg to be released in one cycle.
