Normal or not

Yeslin

So I went to my gyno due to have started lightly bleeding last Thursday to today. She asked if I had not took my birth control pill informed her I have but I started this initial pack late by 2 days and that when I received it I took them right away. She said this is normal especially since it just break through bleeding but I know this isnt. It stop a day then it comes back some days light some days heavy to where I need to wear a panty liner. We made a follow up for next month due to my period is going to start on Tuesday and she did recommend for me to take a pregnancy test before I start my new pack of birth control. I just want to make sure this is normal or if anyone else has gone through this?
