long story short: i had a scan today at 17+4. was scared to death before i went in but everything was fine. baby measuring spot on for where it should be. yawning, turning, wee-ing, swallowing. five more pictures. a heart with all its chambers and kidneys and a gall bladder.
and, a doctor who has agreed to give me scans at 28 and 32 weeks as well as my 20 week scan in three weeks' time, and who told me that any time i'm feeling anxious to phone up and that he will put on my records that i should be given a scan. i love my hospital.
i will do the longer version of this post at the weekend for those who are interested! although it probably won't be as long as it would have been if i hadn't posted this :)
