spotting

spotted about a week before my scheduled period, got my scheduled period, and now am spotting about a week after my period ended. was current on my pill until about 4 days ago and i did miss those 4 pills in a row due to being away from home without it. could that explain my current spotting? any explanation for spotting before my period? don’t think there’s any possibility of pregnancy lol

just looking to see what this could mean in the grand aspect of my cycle. tyia
