Hi, I have been on the pill for 4 months. I started my sugar pills on a Saturday and then I received Implanon the next day (Sunday). It is now a Wednesday, so it s been 5 days since starting the sugar pills, and i still have not had any bleeding. Usually with just the pill I get the bleeding within 2 days. I had a pregnancy test before they inserted the Implanon and it was negative. Could i not be bleeding because of the Implanon? does it work that quickly? Should i take another pregnancy test? Warm regards
