RE appt today

I have an appt with my RE today. After several rounds of clomid and then femara, we are ready to move on to IUI. We've talked about this a lot and know it is what we want to do. But still I'm nervous and hesitant. Logically I know that it will likely be a while before we actually do the IUI and that we've been in this for a long time already, but emotionally it feels so sudden and like such a big step.

I think my hesitation is also due to my fears that it won't work. The planner that I am, I'm already thinking through the next several steps. DH and I both don't feel comfortable with IVF and the idea of having our embryos just hanging around. So right now our plan is that if IUI doesn't work, we will move on to adoption. But then this feels so final as well. What if it doesn't work? Will I be able to face our options then? As we get closer I already have had some different thoughts in my head about IVF. For example, would we think differently if we agree to eventually transfer all embryos? But then wonder I if these second thoughts are just my way to find a rationalization for something I'm not that comfortable with. I know there is a big difference between IUI and IVF both in terms of intensity of the experience and everything entailed. But still I lump them together. The funny thing is, I don't think my worries are that related to the real concern of multiples. I know DH is worried about that. I'm more focused on the fear of what if it doesn't work and what do we do then?

On another note, there is one reason I'm looking forward to this appointment. At our last appointment, she told me it would help if I lost weight, even if I lost 10 pounds. Well, I did that. Actually, I lost 15 pounds since then, but stress-related eating due to a busy period at work and Halloween candy put me back at a net of 11 pounds. I know other people have noticed. Let's hope my dr does as well.
