Kind of an ironic since Adorkable's picture is of her twins!
I'm starting clomid next month and I too have been thinking about the likelihood of twins. I think that's one of those things that you figure out as you go and enjoying the blessings that twins brings. From what I understand triplets and higher order multiples aren't nearly as common as twins for clomid. Good luck! Hoping you just need one IUI as well!
