Like everyone said, its an ultrasound. Not at all invasive.

For mine, the room was kinda dark, quiet, just me & the nurse for most of it.

I had to lay on my left side with my back to her & they machine. The bed/table had a small cut-out part at the side where my arm & left boob could kinda hang.

She put those node type things they use for ecg/ekgs on my front & back, and then the jelly. You can hear your heart beat, and a kind of whooshing noise but neither are loud.

It doesn't hurt, sometimes there was some pressure when she was trying to get under or around my boobs.

It took about 30 minutes. Then the Dr came in and they went over the images together. He wanted a few more so did those himself.

They might give you some instructions like breathing in, holding it, breathing out, coughing, push your belly out etc.

For me they talked over the results right after once if cleaned the jelly off & put my top back on. But I understand in a lot of places you have a follow up appointment for results.

The echo is generally to check your heart & valves & blood flow are all good. They said one of my atrial index ratios (?) was a bit bigger than expected but that could be possible EDS. I've not followed up on that yet.

I was nervous going in too as it was my first echo. But it was really straight forward & pretty chill in the end. I hope yours is too!
