Is this okay?

Okay so I got BC pills from planned parenthood. And then after my first three I asked them to send my prescription to my pharmacy. Well I picked up my first from the pharmacy today and it's a different pill. For three months I have been taking Tarina Fe. And now they gave me junel Fe. Am I going to get new side effects if I take this?  Is my period going to become irregular again? Or is it basically the same thing? I'm supposed to start taking them tomorrow and the clinic is closed so I can't call.
