Birth control pills should I be concern ? Help ..

I started birth control pills again last Sunday the 12th after being off it for about three-four months and ever since I started Ive being spotting everyday now and it’s continuing daily throughout the day non stop ( not heavy ( brownish ) ) should I be concern ? ... I don’t remember this happening the first time I started birth control a year ago .. is it normal ? Has anyone else experienced this ? I’m a little worried i had my full 7 day period same day it ended the spotting started .
