regarding calculating gestational age after IVF pregnancy

[mamhibt]

Dear Dr
I underwent IVF recently. ET done on 13th May. Beta hcg on 28th May was 436 units. On 30th may it got doubled to 996 units. I was called for yolk sac scan after 10 days on 9th June. What would b my gestational age?? How do calculate in case of IVF pregnancy.??? They say it should have been 7wks but its only 5 Weeks after embryo transfer? ?!! I am confused. please advice in this regard.
Yours mamhibt.

Date it from the date of retrieval or if it is a frozen cycle the number of days before the retrieval that was the age of the embryo.
