	$Delete = mysql_query("DELETE FROM blabbing WHERE id='$blad_id' AND mem_id='$id'");
header("location: profile.php?id=$id");

 

How do you know if this query succeeded or failed?

 

Also it's very strange that you have a loop over $_POST, and inside the loop you check if the key is NOT deleteBtn.  And then inside that you use two values $blad_id and $id which are not related to the key you found in $_POST at all.  I don't understand the logic of that.
