At my first ultrasound at 10 weeks, doc couldn't hear babys heartbeat and saw no growth. Told me my baby is dead based on this. Should I wait or get dnc?

D & C. If you are certain of your dates and you should definitely be 10 weeks, there should be a heartbeat. Also, if you are showing no signs of miscarriage (bleeding, cramping, etc.) the doctor will recommend a d&c. A loss such as this usually has no bearing on future pregnancies, and often a cause for the miscarriage is not found.
