What are my chances of having twins?

There are alot of twins in my family. Although I hear it has to run in your mothers side. Is that true? I have two sets of twin cousins from 2 aunts and uncles on my mothers side. My uncles married 2 sisters, so it could be on their side. Anyways, one set is identical, one fraternal. My Aunt on my fathers side also has fraternal twins. Also my brother and sister in law have a set of fraternal twins. My husbands mother miscarried a set of twins also. Are my chances high? None of the women are blood relatives to my mother, and I've heard it has to run in the mothers side, is that true? I am 9 weeks and measuring quite large
