Hi. Don't stress out as in x-ray in this picture appears to be quite ok although a closer look might be required to rule out any hair line fracture. Also please read MRI carefully it says no abnormality that means they are normal.
Next Steps
Once pain and swelling subsides start quadriceps and hamstring strengthening exercises. You should be fine and it will not hamper your pregnancy in any way. Avoid any form of medicine till then
