Congrats on preg!!!!!!

If you are having combined screening test you have bloods done about 10 days before scan.

You generally have bloods for blood group and antibodies, rubella, iron levels, somewhere early on often with combined screen bloods.

Depends on ob if they have a scanner in room my OB does have one and when preg with DS i was scanned a few times due to previous mc but my best friend only got 1 scan in his rooms at first appt.

good luck
