Skipped periods with the pill??

So for the last 2 months I’ve skipped my periods by not taking a break (the placebo pills) an having a period, I just started the next pack. I’ve done this before about 2 years ago on the same bc pill with no problem. For the last week/week an a half I’ve been having what seems like spotting, it can be very light red in color when I wipe but it’s mostly brown like I’m going to start my period but don’t. This month I am going to go for my period and not skip it by starting another pack like before. Is this normal? The spotting doesn’t happen every day and it’s pretty thin an not a ton of it when I do get it, but it’s kind of annoying. I’m supposed to have my period this week but was just wondering if anyone else has experienced this and if so, what is it or should I be worried??
