Does being a fraternal twin increase your chances of having twins?

I am 14, not pregnant, just curious. I am a fraternal twin. There are no sets of twins in my family, not in my generation, my parents, and I don't think in my grandparents. There may be one, though. My mom had an egg placed inside her because her eggs were not working (That probably sounds weird). I know that if you are a fraternal twin than your chances increase because it mean the gene could be passed down along the mom's side, but does it still apply if my mom has someone else donate the egg? Thank you.
