Pill and spotting

So when I get my pills they come w three packs but back in September I went away on a soccer trip and lost 2 of the packs so I had to wait a month for my doctor to send in the prescription again... anyways I finally am back on schedule and I have taken my pill perfectly for the last three months... I was just wondering if it is normal that I am having a super light period or if it’s just spotting thanks!
