I read somewhere that if you are on implanon and using the pill to control bleeding you can get pregnant. is this true?

Implanon: pregnancy would be highly unlikely as you are using double birth control!

Not true: This perhaps comes from the idea that such bleeding indicates decreased effectiveness. There is no real world evidence that this is true. No method is 100% but Implanon provides excellent birth control and taking the pill will certainly not diminish that.
