how can it be that I am pregnant with twins and one is a few days older than the other. I am confused about this can you please explain this to me?

every answer so far is dead on, one thing you will want to be concerened with is making sure it doesnt get to be two weeks diffrence, as it may ,mean that one cord is bent to where its not recieving nutrients as adequetly as it should. DO NOT worry tho, you u/s tech will certainly detect something like that.

It's normal, both of them are right, Ultrasound is off by up to a week. And It'll almost NEVER measure twins the EXACT same! it's normal.... Now if the twins start measuring a whole lot different in age like 1mo older than the other... that's a worry and the doctor will want to check for Twin to Twin transfusion syndrome.. things like that.  but right now when it's so early, it's nothing to worry about at all.

It's just referring to the relative size of the babies, compared to average size.  Don't worry they are not one older than the other.  :)

Every baby develops at its own rate and ultrasound can be off by as much as a week. I wouldn't worry about it since generally they are in the same time frame.
