I have had 3 sonograms so far and they think I am approximately 9wks pregnant which they aren't sure of but that's what it is according to the first day of my last period. The baby has been measuring 4-5wks and isn't growing. The second sonogram showed a faint heartbeat, and my first sonogram there was no sign of heartbeat. Now, I had my third sonogram tonight where all of a sudden a second yolk sac appeared, but still it shows only one baby. Does anyone think I could be having twins? I'm not too sure but isn't that usually what two yolk sacs mean?? Either that or it's a really abnormal pregnancy. Where did this second yolk sac come from though?? If someone thinks it's a miscarriage please tell me. I think it is, but then I have some doubts because of that second yolk sac. Plus, once again the technician couldn't find a heartbeat, but that isn't much of a surprise to me because she couldn't find it during the first one either. Also, I would like to add that my HGC level is extremely high- 50,000. They tested it last Thursday.
