I can definitely relate to your struggle. It is such a tough decision! We decided to do an eSET and were happily successful on the first try. But we were fully prepared to do more transfers if need be rather than transfer multiple embryos because we really didn't want to have twins. In retrospect, I'm so glad. I know many of the moms here have twins and are doing great, but I know that I would not have handled being a mom of two very well. I often feel overwhelmed with just one! So my advice would be to really, really think hard about what the reality of your life will be like if you have twins. If you don't think it sounds right for you, then I would recommend only transfering one at a time. Whatever you decide, I will be keeping my fingers crossed for your success!!
