Scan went well today, despite me waking up from 4am onwards thinking it was time to get up (and then having bizarre dreams about being back at uni, in student accommodation).
Little haloumi is an impressive (to us!) 10mm long, and has his/her own yolk sac accessory and the beginnings of a salacious and commodious placenta. At first, haloumi was difficult to see - mainly because I kept giggling. The extremely young-looking technician was very friendly - introduced herself to El Prima, and asked us if we wanted a picture. And complimented me on my bladder - always an excellent way to make a good first impression. She confirmed that haloumi's looking about the right size for 7 weeks - and has a nice healthy little heartbeat of 120bpm (90 to 200 is normal for this stage, so maybe this means we've got a chilled out haloumi).
(As an aside, El Prima and I are constantly in confusion about how the "weeks" are counted, given that she has a conceptual objection to the standard medical system of counting based on that wacky concept that "week 1" begins with your last period, so that conception doesn't actually occur until "week 3". Admittedly it doesn't make sense, especially when - as in our case - we know down to a few days the date of conception - but I'm all for it, given that it feels like you get a bit of a head start.)
El Prima's going to scan the picture in so we can post it up here tomorrow. Promises to be slightly more accurate than the picture above, but still quite blobby.
