Anyone had a similar experience???

So this cycle I am having a crazy period. It started a week ago with a little spotting which is weird because I have never experienced spotting before a period. 2 days of light spotting then 2 days of nothing and now on the 4th day of spotting again this time a little heavier than before but still not enough for a tampon and only enough for a panty liner. What in the world?!?? Had anyone experienced this? Should I go see a doctor? What could this mean?
