My gynae charges $700 for package from 12th week preg onwards. Package includes: Consultations, urine test, ultrasound scan with pic givin back, for all visits till deliver. As for the heartbeat i rmb my gynae only let me listen to it from 2nd tri onwards.
If you're not comfortable with your gynae, I think you should change to one that you're comfy with if not you will always doubt what she says. =)
