Twins are generally difficult to deliver at full term, which is clinically referred to as 37 weeks, and most twins are born around 36 weeks of pregnancy. This is because twins tend to make the uterus too large and therefore can easily lead to premature rupture of membranes and premature labor. In addition, compared to pregnant women carrying a single child, pregnant mothers with twins have larger bellies and are heavier, which puts more pressure on the pregnant mother’s body and can easily lead to complications. In addition, twins also interact more with each other, which will indirectly stimulate the pregnant woman to produce contractions frequently, which is also the reason why twins are more likely to be born prematurely. It is recommended that pregnant women with twins should reduce their activities at the end of pregnancy, have regular checkups, and take ferrous sulfate and calcium supplements.
