Pregnancy, Premature babies and Twins

Patient: If my husband and i were both born prematurely, are we at a higher risk of our baby being born premature? Can having injuries to my hips affect me during labor? If my husband is a twin and my generation is due to have twins, and my husband has twins on his moms side every generation and on his fathers side is every other generation are we going to have twins? What are our odds of having twins?
