First time!

So today I finally put a cloth diaper on my baby. I used the Alva diaper in size newborn, her legs are still pretty thin. Well it almost worked out great... no leaking through the diaper or through the legs, but there was leaking through the top. Up towards her belly. Should I raise it higher? Is there a reason the pee went up?
I had the top of the diaper right below her belly button FYI .
