Abnormal brain MRI

I guess im just looking for a piece of mind or some similar stories, I had my son in July and since I had him I developed awful migraines (they thought from the epidural) I went for a brain mri last week to check everything out, I wasn’t supposed to go back till December but they called and pushed my appointment up to tomorrow to go over his findings. I’m honestly worried sick, and I just need some advice or some thoughts.
