Period on mini pill

I'm on my second month of mini pill, after the first month I discovered the last 7 pills weren't placebo (I only skipped one of those bc I was tired one day but now that I know that they don't have placebo I take them all on time).

The first month I had a light bleeding for 6 days, and now on the second month I've been having the same light bleeding for 3 days now.

Is this normal? I'm on Camelia and for what I've seen online most people that take it don't get a period/bleeding. I want to make sure if it's ok or if the pills are failing or something since I don't use condoms with my bf
