Portia substituted for Levora?

Quick question! I specifically requested Levora for my first BC prescription because my sister had used it but I got to the pharmacy and got Portia instead. Does this mean that it’s the generic version or is it something a little different? The Levora pack is much easier to use. My sister passed last fall and had two full months of it that I’m going to use and then open my three months of Portia if that’s not too crazy. I hope my body won’t freak out like I’m switching brands when I go from one to the other
