Miscarriage Risk with Twins?

I’m pregnant with twins. When does my chance for miscarriage drop?

Re:

The Bump Expert

Most miscarriages occur in the first trimester and are due to chromosomal problems that happen during fertilization. Unfortunately, multiples do carry a greater risk of mis-carriage than singletons throughout the entire pregnancy. According to one study where ultrasounds were performed early on in pregnancy, about 9 percent of twin pregnancies result in the loss of both babies, and in 27 percent of twin pregnancies, one of the babies is miscarried. If those numbers seem high, keep this in mind: After week 20, the risks go down significantly, and moms carrying twins have about a 90 percent chance of delivering two beautiful babies.

Most miscarriages involve bleeding and/or cramping. But -- and this is important -- if you experience bleeding in the first trimester, don’t panic; more than half the time it stops and the pregnancy continues to term, so take a deep breath and call your doctor to explain your symptoms. In some cases, there are no warning signs until an ultrasound reveals no heartbeat (this is known as a “missed miscarriage” when the entire pregnancy is lost and as “vanishing twin syndrome” when one of the babies is lost).
