Hey girls, well I got it done.. they actually think im earlier than i thought i was.. they estimated between 4-5 weeks.. so no baby or heartbeat was seen BUT they said I have a perfectly rounded sack and yolk sack! yay- thats a good start! And so now i have to wait about 2 weeks to get another one and hopefully see little beating heart!! HCG levels were at 910 on friday so im thinking im about 5 weeks with that level! p.s.... IF i WAS having twins (way out there to know now i know) would you see two yolk sacks or just the one?? hmmmm
