Thanks ladies and yes it is a confusing, but cant wait to find out what I am having , and for them to get here.
If you want to, you can count out 266 days on the calendar from the day the eggs were transferred plus how old they were when frozen. In other words, if they were 3-day embryos, start the count beginning on June 7. If they were 5-day embryos, start the count on June 5. A full-term pregnancy is considered to be 266 days from conception. (280 from first day of last period). Don't be surprised if the twins don't come on time, twins are often early. Good luck!
