I have had my Nexplanon for 5, almost 6 months now, and I did not bleed for the first month at all. After the first month I bled every day for 4 months straight. This past Saturday, the bleeding had stopped all together. I have had some light pink spotting or brown blood for the past few days, so I took 2 high-end pregnancy tests and both tests came out with the results of Not Pregnant. Is this bleeding pattern normal? Is it likely for me to be pregnant?
