Postpartum Spotting

I am 4 months postpartum. I had my first period at about 7 weeks postpartum and have been using this app to track them. I’m on Mylan(it’s a pill) for birth control. I have been spotting consistently for a month. I’m almost tempted to stop my birth control and see if that is the reasoning behind this. I also have to have a LEEP procedure done to see if I have cervical cancer and just recently had a cervical biopsy done. I’m just tired of the bleeding. Please let me know if any of you have experienced this!!!
