I am so happy for you, how exciting!
I could relate to your worries. That initial 2ww is nothing compared to getting to when the flutters and then the kicks can be felt. I don't think I let my breath out until week 18 or so and even then I would watch for enough movements to give me comfort.
After going through IF and finally being pg, it's hard to just be zen about it all.
Post any time you feel the need. I am sure many women were vigorously nodding as they read your post.
