Continuous birth control

I take Marvalon 21, typically I don't take a week off and I start a new pack and I miss my period. I've done this since I was 16. For a long time id stop and get my period every 3 ish months. But in my adult years it's been easier for me to just not get a period.. so i haven't had a period since maybe 9 months to a year. Aside from some light spotting about 5 months ago, when I was going to get a period but then started my pack again and didn't get a period. So here's the question. I had my last pill on Thursday , I started spotting two days ago. Today closer toward the evening the spotting was a little heavier , thus assuming that tomorrow it'll be an actual period rather than just spotting. But tomorrow is Thursday. Should I start my pill anyways and not get an actual period or should I hold off a little longer , bleed a bit and then start after having a period for like 2 days or something ? Or will that mess my birth control up ?

My period is taking longer to be normal cause my hormones are out of whack from taking it the way I do.
