She's probably fine but without examining her myself I cannot be sure of that. If you are worried about her you should have her checked out by your vet. As a side note, 11 months old is very young to have had kittens already. When breeding cats it is recommended to wait until they are 18-24 months of age. If she is not a breeding queen I would suggest you have her spayed in order to avoid future aggressive behavior.
