So sad to see our numbers dwindling all the time. 
and good wishes to all.
Very jealous of those of you with such clear scan pictures already. None of DS's look like much of anything, even the ones much further down the line. He just wriggled about all the time, so his pictures are all blurry 
blonde I kind of have a good bleeding story. Bit of a good news/bad news one anyway. With DS I bled loads between what I thought were weeks 7&11. My scan date when it came through would have been too late for the nuchal testing so I rang up and got a cancellation.
This turned out to be a bit of a mixed blessing as it turned out I was only 8+3 (ironically too early for the nuchal testing) and the scan took ages (there was a trainee initially, the the supervisor took over without saying anything to me/DH). I was panicking, but DH was oblivious as he was sat at the end of the bed and he'd seen a wriggly little bean with a good strong heartbeat!
The complication was there was another sac measuring 6+1 with no heartbeat. If I hadn't gone in for that scan I would never have known that we'd "lost" a twin, it was a very surreal experience. The lost twin just sort of got reabsorbed. I never had any more bleeding, and by the next scan there was no sign or it.
I was so relieved that I was still pregnant that I still dont feel as though we lost anything. Which is lucky because with the exception of the MW's in the delivery suite EVERY SINGLE heathcare professional who saw my notes after that said "ooh twins, congratulations!" and I had to correct them every time. 
Oh, and we were told that the loss of one twin could reduce the accuracy of the nuchal testing se we didn't bother with it in the end anyway
Anyway, bleeding not always a sign of impending doom, and often there is no explanation. That said, If you're worried contact your EPU.
