I had a very early scan (due to a clerical error!) at what I thought would be 8w, the baby was measuring 6w2 but my periods are irregular so, no big deal. 11 days later and another scan, the baby is only measuring 6w5. It has a heartbeat of 120bpm but 3 days growth in 11 days doesn't seem excellent. No bleeding or cramping (although now, of course, I'm convinced I'm cramping). My boobs have been less sore and I've felt less sicky over the last couple of days...
I'm not much of a catastrophiser but can't see a way this can be OK?
