Obgyn yelling at you?

So my obgyn came into the room to do an ultrasound and started going off on me for "being pregnant". She didn't check my blood test or anything to confirm it. I had a molar pregnancy and my hcg hit zero in august and she said we could try again this month. She completely forgot everything and started YELLING. I didn't know what to do. At all. I just sat there and told her I needed to get checked out because my pregnancy test was weird. And she gave me an ultrasound but not with the probe. It was the tummy one. If I'm early on she would have to use the probe one. In the end I feel like it was unprofessional and not thorough. What's your thoughts on this? How would you have reacted?
