How can you tell where placenta is?


I asked the tech where the placenta was on the ultrasound and she said that its not something to worry about this early on. I had anterior placenta with my first but not with my second, so i was just curious. She was kinda rude. Im going to request another tech at my next appointment.

I circled where my mom thinks it might be but im not sure if thats it or not 🤷🏼‍♀️🤷🏼‍♀️
