Pregnancy can be a very exciting moment for a woman, much more if she knows that she will be having twins. Having twins can double your happiness and your giggles. Besides the fact that twins are cute, you will have 2 or more babies within one pregnancy. But of course growing two babies in your womb would require extra care and precaution. There are things about multiple pregnancy that a woman should know. These things will help her prepare for a risky pregnancy. If a woman has a familial tendency, or if she is on a fertility drug regimen, the chances of conceiving twins is more likely. Thus, she must be evaluated first by her doctor before she decides on getting pregnant.

By definition, a twin pregnancy is a pregnancy in which the mother is bearing at least two babies inside her womb at the same time. Twins who look exactly the same are produced by the splitting of an egg to two different cells after fertilization. This kind of twin is called identical. They have the same sex as well as similar faces. The other kind of twin pregnancy is referred to as fraternal twins. This kind is produced by the two eggs that are fertilized by different sperms at exactly the same time. They may have different sexes and different appearances.
