Lap Desks that fit over belly

Stephanie
Hello everyone,
I've been having terrible upper back pain for months during this pregnancy and finally got a note to work from home until the baby comes. Looking for recommendations on a desk/tray that would sit on the bed, can hold my laptop, tilt, and fit over my belly for the remainder of my pregnancy. I see a ton on Amazon, but want to be sure there will be enough room to clear my bump. I bought a stand on wheels but my bed and belly were too high. I am not officially on bed rest but the only way I can get relief is laying down propped up with some pillows.
Thanks in advance!
