Twins ???

Emily • I am 22 ,I`ve been raising my husband son for 3 years now he`s 5.This will be my first pregnancy :)
My husband uncle is a twin , his grandfather was a twin . My uncle was  a twin as well. I have two sets of twin cousins. Is there a high chance I might have twins ??? His bothers had kids already and none of them had twins .. I'm so nervous ! I would like twins :)
