it's fairly unusual (i think) to see scans prior to 12 weeks, only because they're not routine scans unless you don't have a regular cycle and need a dating scan or you've had some bleeding. our second scan was done at 8w3d to confirm that all was ok as i'd stopped all ms for a couple of days (came back with a vengeance though) and because it was an AC pregnancy so the FS was prepared to do a second scan. the first was done at what we thought was 6w1d but measured 5w3d, and that difference worried us all a little in case bub wasn't strong enough. i think it was just resting early and waiting to make it's presence properly known a bit later!

fwiw -
5w3d - 99bpm
8w3d - 186bpm
12w1d - 152bpm

Tanya, i'll have a squiz at other photos later and upload if there is a full body profile. pretty sure there isn't though - cept maybe the heartbeat trace one which would have bub fairly small
