So what is your chance of having more than one baby at a time?
Basically, it is 3% or 1 in 33.
There are things that can increase your chances of having a multiple birth, including a mother being 30 or over when she conceives. For example, while there is a 3% chance of having a multiple birth at age 25-29, it increases to 4% at 30-34 years and almost 5% at 35-39 years.
Other factors that can increase your chances of having twins include having a maternal family history of multiple births (fraternal), and of course, using fertility treatments (in vitro fertilization or fertility drugs).
Your chance of having twins is also influenced by your race (multiples are more common in African Americans and least common in Hispanics and Asians), how many times you have been pregnant (the chance of having twins increases with each pregnancy), and whether or not you have had twins already.
Keep in mind that statistics for birth rates and multiple births include all births, including those that were the result of fertility treatments and those that were spontaneous or 'natural'. So if you don't have any of the factors mentioned above that can increase your chance of having multiples, your chance is going to be a little less than 3%. The chance of having 'natural' fraternal twins is only about 1.7% or 1 in 60. The chances of having twins with the use of fertility treatments can be as high as 20-25%!
Of multiple births, the rate of fraternal twins has been increasing the most, and that makes sense since the chance of having fraternal twins is influenced by an advanced maternal age and the use of fertility treatments.

There is two types of twins. Identical and fraternal. Identical twins come from the same egg and the same sperm. They will always be the same gender and have the same DNA. This type of twin is NOT inherited. Not at all. Every woman on the planet has the same chance of having identical twins.
Fraternal twins are different eggs and different sperm. They will be as much alike as any sibling (except they share a birthday)
This type of twin is inherited but only through the mother's side. (mom, mother's mom, or grandmother's mom, etc) It happens when the mom drops more than one egg. If your grandmother occasionally dropped more than one egg then it is possible that your mother does too and you as well. If there is fraternal twins in your husbands side of the family or your father's then you do NOT have a greater chance of having fraternal twins. The man, after all, has nothing to do with how many egg a woman drops :-)
So...it depends on what type of twins because it sounds like they do come from your mother's side.

The Chances Of Having Twins
From The National Parenting Center
About 1 in 26 births are twins so unless you have undergone fertility treatments, which do increase those odds, it is still a long shot that you will have twins. Of the twins born in this country, 75% are fraternal and 25% are identical. Fraternal twins tend to run in families and various fertility drugs also increase your chances of having them. Fraternal twins may or may not be of the same sex.
There are no known causes for identical or one-egg twins. It just happens. These twins are always the same sex, the same size and often they have very similar temperaments. Strangers will have a hard time telling them apart. And, although they may look and act alike, they are two separate, distinct human beings and should be treated as such.
At birth, your doctor can usually determine whether you have fraternal or identical twins, but not always. You will know for sure after a few months. They will either continue to look identical, or they'll develop important physical differences in appearance.
Twins are twice as much work, but also twice as much fun. Oh, and if you think you may have triplets count yourself in a real minority: the odds of having three children in one birth are 1 in 7,000!

Probably not. Twins usually skip a generation. HOWEVER....
My grandfather had twins in his siblings. My grandmother had twins in hers. Together they had a set of twins. My mother had 3 sets. (Yes, I said 3!!)....So far no one in my generation has had twins, but there are several young people in my generation of the family that have not had kids yet....
You never can tell....

Identical twins are based on genertic history
Fraternal twins, are not. The number seems to be changing over recently years.

It depends on if your aunts are identical or fraternal twins. Fraternal twinning can be hereditary.... identical twinning is not.

Don't know any numbers, but the chances are higher with a family history, also higher for people of African or Native American ancestry.
