There different types of twins, they can be in the same sac or separate and they can have their own placentas or share a single placenta. I think she would have said something but it's possible she missed it, I would ask at your next ultrasound definitely! @njja53

I just looked it up and apperantly it is possible but the lady didn't say anything so now I'm wondering lol @rennysmommy

I know I was thinking the same thing but I didn't think that was possible? I know twins share the same sac @rennysmommy
