No, most pregnancies do not start out as twins. When the ovaries release two eggs and both are fertilized then will twins be born (fraternal/nonidentical twins). Or a fertilized egg may divide before implantation resulting in identical twins.
if you are 4 months along then the baby will still be born, it will just not be alive when it comes out. Although most pregnancies are twins when they first start out, usually one of the two babies die.
maybe. most pregnancies start out as twins very early on, but one dies right away. The stronger one lives. so I guess it depends how far along in the pregnancy your mother was. twins do run in families. are there other twins in your family? aunts, uncles, grandparents? that would make your chances of twins higher. Twins run on my aunts side i figured it wouldn't affect me.
Hyperemesis is seen more often in first pregnancies and multiple pregnancies (twins, triplets, etc.)
Usually one, occasionally two although twin pregnancies generally abort before birth or one foal is dead at birth or dies shortly after birth. Often both twins die. Successful twins are rare. Most breeders use techniques to prevent twin pregnancies.

I have had two pregnancies including a set of twins and had heartburn with neither. I have a friend who has got through a bottle of Gaviscon a week from 16 weeks with all four of her pregnancies. It depends.
For many woman it does, it did for me, but not in all of my pregnancies.
Yes, the Twins were founded in 1961.
Twins are by definition TWO. Any other number and it isn't a Twin birth. There's a considerable random element to Twin pregnancies, so there's no actual limit to how many Twin pregnancies a woman can have during her fertile years. Any pregnancy can be a Twin pregnancy.

Para on its own -- not as a prefix -- means the number of live children a woman bore. (Gravida refers to number of pregnancies). So a woman who had two pregnancies and three children (a set of twins) is Gravida 2 Para 3.
