why am i bleeding between my periods?

my period finished three days ago and this morning i started bleeding again, i was wondering why that would be. i quit smoking about a month ago and i was thinking its because of that.
so could anyone help me figuring this out?

Bleeding or spotting between periods can be a frightening experience. You never know when bleeding between periods may occur. Maybe your period was over last week and then you notice that you're bleeding again. Maybe this isn't the first month you've experienced bleeding or spotting between periods. Or it could be the first time you've had bleeding between periods. Whether it's the first time you've experienced bleeding between periods, or just another month of spotting, bleeding between periods is a frustrating and stressful experience.

It's called spotting or break-through bleeding. It's actually fairly common and perfectly normal.
