Close to Dec. 20: If the ultrasound dating is up-to-standard accuracy then sex around Dec. 20th would be most likely. If sex was only Dec. 9 then that would be it, although that suggests the US dating may be off by a bit more than usual. Nov. 25 would be impossible as a conception date. Dec. 20 +/- is your best guess.
