Expert Q&A

I am almost 21 weeks pregnant with twins. How are they proportioned in the uterus? I keep seeing the singleton and am wondering where are mine fitting?
It truly is amazing how the human body, and especially the uterus, accommodates in the circumstance of twins. Generally, healthy twins will grow at the same rate as singletons up until the late second trimester. In the third trimester, the growth acceleration isn't as rapid as singletons, so twins will often be a little smaller than a same gestational age singleton. At any rate, by the third trimester, there is a lot of baby. So the uterus just grows and stretches to accommodate the size it needs to hold the pregnancy whether it be a 10-pound singleton or two, 5-pound twins.
