D.D.
Go see Dr. Bill Schoolcraft and Dr. Eric Surrey (they have two other partners as well) at Colorado Center for Reproductive Medicine. They have been rated year after year #1 in the nation for fertility and we are lucky enough to have them right here in Denver. It is an amazing thing to sit in the waiting room with couples from Australia, Japan and all over the world....we just have to travel a few miles...again, lucky us! They just opened a new office down near SkyRidge. Everyone in the office is super nice and they really know their stuff.
I'm 46 and they helped me have twins...now 4 months old!
Good luck, D.
