birth control pills questions please answer !

I'm on alesse 28 in curently on my third pill pack and right now on third sugar pill! I started spotting but it was a little more than spotting the last week of active pills and it got lighter now but hasn't stopped so it's been basically 8-9 days now and haven't gotten a period If that spotting isn't a period and I'm worried if that is normal ? And if I'm still adapting to it it if the pill isn't working! Please let me know if you had the same problem before and also if this is normal??
