Other than possibly the option presented above by Megan there are no further ultrasounds unless there becomes a medical reason why your doc needs to send you for one at a later date. A standard normal pregnancy will generally only have at most one at 7 weeks (if not sure of dates), one at 12 weeks(NT scan - if your eligible or choose to have it) and then the one around 18 weeks (the anatomy scan) - the next time you'll see your bubs will be at birth
