If I knew you were coming I'd have baked a cake

Last night, I took my CF card out of my camera without turning it off.  And then I put it back in.  When I went to turn the camera on, I realized that it was already on. My card said "No images".  I formatted it and used it today to take pics of coloring easter eggs and making a cake.  When I went to download them, it said "no images".  YIKES!!! I was able to transfer the images via wifi to my phone, so I have them, but is the card bad now?  I reformatted it and took a pic, which was readable on my computer.  I'm a little nervous about the card now, however.

And I decided to make a cake for Easter dinner.  From scratch.  I cannot remember the last time I made a cake.  It should be good.  The extra is my colored eggs.
