Can someone interpret my results?

I'm really worried about my result of my ultrasounds. I'm 24 and have been TTC since my miscarriage in January

2021. My periods come every 3 weeks and usually last

8-10 days so I knew it was time to figure out what's going on. I should have done it sooner, I know. I did get bloodwork as well but waiting for that to come back. Can someone please interpret my results? And if anyone has anything similar to these findings - how has TTC been for you? Is it curable? Anything helps. Thank you
