Anxious- I totally understand how you feel. I told some close friends and family as soon as I found out I was pregnant (they knew we were doing IVF so hard to keep the news in

After we heard the heartbeats we told a few members of our extended family and since my pregnancy is very high risk (expecting identical twins!) I am waiting till 12 weeks to tell what DH and I call the "gen pop". I would bet multiples with an initial beta of 709- what dpo is that?
Neffi- very high betas can indicate twins, however I have seen low betas with twins and high betas with singletons. It really depends! But I think an inital beta of over 400 typically indicates twins.
Sita- I hear that! I am having identical twins so will not be returning to work. Depending on how the pregnancy goes, I may leave fairly early into the pregnancy...however I get paid a bonus at the end of the year so it will need to be worked out with my boss.
Faith- congrats and welcome! Don't stress too much about betas. Docs want to see a 60% increase and that is perfectly normal. I increased 83% over 2 days for my second beta and FREAKED! But then doubled my next beta and ended up with identical twins. Betas don't mean too much!
AFM- had my first peri visit (high risk OB visit) this afternoon and all is well with the twins. They are both measuring around 6.5 weeks (I am 6w6d) I was a little concerned that twin B's heartrate was only 114 (twin A was 133) but the dr. said it was fine and anything over 100 was healthy. Back in 2 weeks to determine whether the twins will have separate amniotic sacs (since I have two yolk sacs there is about a 95% chance they will have sep amniotic sacs) so I am happy about that. Feeling tired and nauseous all the time but happy to feel sick as long as the babies are good!
Heather, Lisa, Brandi, Sarah- how goes it with you ladies?
