Hey there. Sorry for not responding earlier to your post. My desktop here at home was giving my problems so this Computer Dude came over and after 2 hours still could not get it running properly, so he took my hard drive home to finish up ande I have been without internet for nearly 2 days...finally tonight I couldn't take it anymore and got out my 8 year old laptop...
To answer your questions - my 1st u/s was at 5 wks/3 dys and the only thing my RE saw was a gestational sac. He did not see any yolk sac or fetal pole. He then said he saw "something else" possibly a second sac, but it was not clear. I went back a week later, at 6 wks/3 dys and he saw a complete baby - gest sac, yolk sac, fetal pole and the tiny flickering heartbeat. He also saw a second gest sac with yolk sac. I go back on the 24th for a 3 u/s, to see the progress of both. By then there should be 2 heartbeats, but could also be just one still. Only time will tell.
At your next u/s you should see more. It is quite common to only see the ges sac during early ultrasounds.
Good luck and keep me posted!
