Laura,Sorry your appointment didn't goes as well as you'd hoped. I'm glad your Dr is willing to go ahead and do the heparin. I wonder if he recommended IVF because of chromosomal issues. With me all my testing has always came back normal so my RE recommended IVF so they could do biopsy on the embryos as they developed and only use the go ones. Don't remember any technical names of any of it,sorry. I 'll be praying you don't have to go that route. I don't think we will be.
