Mothers who are pregnant with more than one baby need special care.
Having more than one baby may happen more often if:
The most common cause is when two or more eggs are fertilized by two or more sperm. These babies can be either boys or girls. They may or may not look alike. They are called fraternal twins or triplets, etc.
Less common is when an egg is fertilized by a sperm as usual. Then, for some reason, the egg splits apart. Two or more babies grow. They are the same sex. Their hair, eyes, and skin will be the same color. They are called identical twins or triplets, etc.
In rare cases, the egg doesn’t split apart all the way. The twins stay joined together at the head or back. Or they may be joined at some other part of the body. They are called conjoined twins. Sometimes surgery can separate them after they are born. This can be very risky.
At first, a woman may not know she is carrying more than one baby. Her health care provider can usually tell within 8 weeks. Signs include:
The health care provider watches for risks that come with carrying more than one baby.
Some mothers can have a vaginal birth with more than one baby. Others may need a Cesarean section (C-section) for a safe delivery.
With vaginal bleeding, do you have any of these signs?
