Timing First scan

Lis

Hi all

Just wondering when is a good timing for the first scan? My Hcg is going up quite well so far.. 682 at day 12 post transfer and 1804 on day 14 post transfer ☺️. I was really hoping to have my first scan next week when I’m 5 weeks and 6 days (23 days post 5 day embryo transfer) however my doctor wants to do my first scan only after week 7. Would you guys recommend to have a first scan on week 5 (almost 6) or is it too early? Many thanks!
