your sessions aren't set because haven't specified want start them.. need add top of every script plan use sessions in.

session_start(); 

further more, @user4789619 stated in answer, can't re-declare $row variable that.

another note, if want check rows returned did

if($row > 0) {... 

you need check rowcount doing this:

if($stmt->rowcount() > 0) { ... 

^{read more rowcount()}

further more, you're mixing whole range of stuff won't work. you're fetching data pdo::fetch_assoc associative array, yet you're trying call $row->nome; object.... on top of that, aren't selecting rows... select email, senha login
