We had ours at our first appointment with our OB which was at 10 weeks. Unless you have a history of problems, my OB won't see you until 10 weeks. I think it was a great time as there was a definite heartbeat not to mention DD acutally resembled a baby, albeit a tadpole baby. LOL! Our next scan was at 12 weeks then 16 then 20 then every appointment with the OB from there.
