If the person is very young, and at the same time she is very small in size, then there are always chances that her uterus to will be small in size, as all the organs have to fit in the small sized body.
a pubesent female's uterus is about the same size as a naval orange.... a pubesent male's uterus, however, is 6 times that size.
The problem with multiple births is that there is only so much room in even the most accommodating womb (uterus). Babies need to reach a certain size and gestational age before they can survive outside the uterus.
The uterus is the female reproductive organ that holds the fetus during pregnancy. When you're not pregnant, your uterus is about the size and shape of an upside-down pear. The inner walls of the uterus are lined by the endometrium, a layer of tissue, which nourishes the fetus during pregnancy. In a woman who is not pregnant, this lining is shed each month as her menstrual flow. The walls of the uterus are made up of smooth muscle. The contraction of this muscle tissue allows a woman to give birth.Fibroids are non-cancerous tumours, which develop on or in this muscle layer. The medical name for fibroids is uterine leiomyomas. A fibroid can be as small as an apple seed or as large as a melon. Doctors talk about the size of a uterus enlarged by fibroids the same way they talk about the size of a pregnant uterus. So when a fibroid stretches the uterus to a 12- to 14-week size, the uterus is about the same size it would be if you were 12 to 14 weeks pregnant. This refers to a fibroid about the size of a small melon, or to several smaller fibroids.
When you are not pregnant your uterus is only about 3 of 4 inches, or about the size of your fist. The human uterus in a non-pregnant woman is about the size of her fist, but during pregnancy it can expand hundreds of times! weighing just a few ounces.

If you aren't having periods, then it's quite unlikely that you will get pregnant.

The puerperium is known as the period of time when the uterus returns to its normal size.
The size of a normal uterus depends on the animal it belongs to. A human uterus will be larger than a dog's for example.
