UNDERSTANDING WHAT YOUR CHANCES CURRENTLY ARE
Understand that the average person's chance of having twins is about 3%. Not so high. But it is highly probable that you are not average. If you have any of the below, your chances increase.
If you have a lot or all of the below, your chance gets higher a lot. The opposite is also true, if you do not have any of the below, then the chances of you having a twin are extremely low.
Having twins “in the family,” especially on your mother's side. Iif you already have twins, the chances increase quadrupled.
People of African descent are known to be of the highest probability to conceive twin kids. These are followed by Europeans. Caucasian and Asians have the lowest chance of having twins.
Your chances are better if you are tall or well nourished, or even overweight.
It also helps if the woman has been pregnant before. Women with 4 or more pregnancies increase their chances of twins dramatically. It seems that the body is more likely to have twins after it knows you “can take it.” In the families that have a dozen children or more, the numbers of twin births are much higher as they have more pregnancies.
