Is this normal?

Just out of curiosity, but I am worried because I started taking birth control almost a year ago and was prescribed Lutera. About two months ago, I picked my prescription up and it was changed to one called Aviane. I thought it was weird that it had changed to a different one and I was worried, but I just took them because I felt they had the same effect. Anyways, I pick up my prescription today, and it’s ANOTHER brand called Lessina. Is it normal to have three different kinds of birth control prescribed like this? Will it mess me up in any way?

As an fyi, I am calling my doctor tomorrow to bring it to her attention and see if it’s something that she did and if not, then ill talk to my pharmacist and see if they had messed it up somehow.

Thanks in advance! 😊
