Birth control interactions

Patient: I have had the nexplanon birth control implant for 6 months and have had bleeding/spotting the entire time. My regular doctor recently prescribed me a birth control pill (estrogen and progesterone) in addition to the nexplanon to see if it would stop the bleeding. I was unable to have a detailed conversation with her about it. Is there anything I should worry about taking the pill while still having the implant?
