CAN I GET VISITATION FOR A CHILD THAT IS NOT BIOLOGICALLY MINE? EVEN IF I NEVER MARRIED THE MOTHER?

I WAS TOLD I HAD A TWO YEAR OLD DAUGHTER I HAD BEEN VISITING THE CHILD AND PAYING SUPPORT. MY EX GIRLFRIEND AND I WENT BACK TO COURT OVER HER MOVING AWAY WITH THE BABY. THE JUDGE ORDERED A DNA TEST AND IT CAME OUT I AM NOT BIOLOGICALLY THE FATHER. DO I HAVE ANY RIGHTS? I HAVE BEEN IN THIS CHILDS LIFE FOR TWO YEARS!!
