Is Light Bleeding Normal While Being On Loette Pills?

hi im just started using Loette this month, i have never use any pill or contraceptive before.
i started taking the white pills during my period and taking the pink shaded area as soon as it stopped. About 10 days after i started taking the pink pill, i started to bleed again, just a tiny portion, but not really spotting. i still take the pink pill and now im down to 3 more pink pills, and still bleeding, even its not as much as my normal period.
My questions are :
1. is it normal ? do i need to be concerned ?
2. should i continue to take the pink pill until it over ?
3. should i take the white pill on the 2nd strip or should i take the pink pills again ?
