I just started birth control on May 29. I noticed bleeding on Tuesday (June 12) and was told by my doctor that it is breakthrough bleeding and not an early cycle like I thought it might have been (it's due next at the end of next week). I was also told that this bleeding should only last a couple of days. This is the third day and I seem to be bleeding more and not less. Before I bug my doctor about this, is this normal and how long should I wait for it to stop before I call my doctor again?
