Abnormal discharge

Hey, ladies. I hope anyone can help me here. The situation is so that I started taking my contraceptive pills for the 1st time in my life, then I stopped for a month and started taking again daily and on time.

It has been 2nd month now and every time in the middle of my cycle I started having brown discharge , sometimes with a small amount of blood for like 4-5 days.

Is it smth normal or a must consult doctor situation?
