Kinda bummed

Went to my doctor yesterday for my 13 week visit. Expecting to get an ultrasound since I haven't had one yet. The doctor uses a fetal Doppler we hear the heartbeat and then nothing. I asked him when I was getting one and his response was that I'm only getting the one ultrasound when we determine the gender. And that's usually the only one parents are really wanting to know anyways. After him saying that I became pretty bummed I won't see my baby before then. Granted he seems happy with how things look but still. It seems odd to me that he wouldn't want to look at least more than once. Is anyone else's doctor like this?
