JodyC: My first U/S was on April 28 - the gestational sac measured 6.3 MM
I will have my second U/S on May 5 - I think the doctors like doing this because they told me that even if they couldn't see anything b/c it was too early they still want to look.
Minouche: Thanks.
Tmerone: Thanks. I don't know about multiples b/c it's possible. My doctor transferred 4 embryos on April 9th. It's too early to tell but my doctor did see ONE gestational sac on April 28th. I should know more May 5th ~ keeping fingers crossed. I've never in my whole life seen a number that HIGH before. I'm in total shock. My doctor said that number was excellent.
