I think identical twins are or can be determined by the father but fraternal is defiantly decided by the mother
Im 6 weeks and two days and having twins and its not in my generation at all
Yea the baby daddy has nothing to do with the twins. And excessive eating isn't a sign. One sign could b excessive vomiting but even then you don't know until you see a doctor.
As far as I know it has to be your generation (not your husbands) expecting twins because you are producing the eggs and without the eggs there's no way a sperm can do anything.
