My Daughter Is 14 Years Old. She's Been On Birth

My daughter is 14 years old. She's been on birth control pills for 2 months l. At first the pills was fine, but know she has been bleeding for almost a month and I don't know if it's the birth control pills getting in her system or it is it a bad for her body. So I made her stop taking them to see if the will help with the bleeding.
