I need help !!!


I started birth control the pills , two weeks ago it’s the lowest one and I just started bleeding Tuesday September 15th 2020 , and I’m still bleeding September 21st 2020 so I’m trying to figure out how long am I suppose to bleed ? I think I had my period because I didn’t have one for this month and I took the pill at the end of August which was before my next period in September.. I basically just wanna know HOW LONG AM I SUPPOSE TO BLEED .. I thought the bleeding was suppose to be short
