Can you hear baby heartbeat at ultrasound?

Hello ladies can you heard a baby heartbeat when your doctor does a ultrasound? I literally had to delete a post because apparently you can’t pick up a heartbeat at 9 weeks or on a Ultrasound is what this lady was saying I wasn’t about to argue with her lol. When I was pregnant with baby 2 I was around 9 weeks when my ob pick up a heartbeat I mean I try explaining that to this lady I mean my ob clearly knows what he’s doing I seen him with all 3 of my pregnancy’s I no reason to lie about this plus I know a bunch of other pregnant women who have said there ob picked up a heartbeat at 9 weeks almost 10 weeks.
