I know it's hard to wait but you really don't need one at 10 weeks... Wanting one is normal. If I had my way I would buy a sonogram machine and look at my peanut all day every day. You can pay for one at a 3d /4d place but the ones by me all recommend waiting until at least 16 weeks to get the best pics and usually won't schedule you before then because they are not supposed to take the place of a medical scan
You could always look into the 3d ultrasound. You find to find a place that does them and pay. But they are pretty cool and you see a lot more with them. Or you can just try to be patient! Lol I know it's hard
