Just a quick update.... after stressing myself to beyond nervousness, the bub was there plain to see on my first scan today. In fact, DH was so excited and kept babbling and babbling to the doctor, and eventually I had to tell him to be quiet for a while so the doctor could do his thing and take measurements. Quite clear to see the sac, the little fuzzy bean-shaped blob measured 15.33mm, and the heartbeat flickering away brightly. I asked the doctor what the heartbeat rate was, but he's just a temp (as my FS is away), but he said it's definitely over 100bpm as he could tell by how fast it was flickering. They're taking my EDD from 14 days before IUI, as opposed to day 1 of AF, so my adjusted EDD is now 27/8/15 and today makes 7w5d, even though on the scan bub is measuring 7w6d.
I was expecting to cry, be emotional and had told DH he would need to hold my hand, but strangely I didn't feel like that at all - it was kind of like an out-of-body experience, rather weird. Very relieved and happy, to say the least, but I so wasn't expecting to feel sort of removed from it. I think it just still doesn't feel real :-))
