ok so I'm having twins one is 18-2 and the other is 17-4 I don't understand this is one twin a week younger than the other one please help
It can happen so try not to worry as well as they can be conceived at different times as well as have different fathers ( I'm not saying you were with different men) just explaining what I heard
What @reaganmommy2015 said, or it could just be that one baby is measuring bigger than the other!
