First scan at week 10

Hi, wondering if I can get some expert advice. I'm currently pregnant with my first pregnancy, conceived with oral fertility help (Letrozole) and NUH schedules my first scan at around week 10. Is it ok or is too late for a first scan? Because initially i thought first scan is around week 6-8? Appreciate any advise. #firstbaby #1stimemom #pregnancy #pleasehelp
