Hi Cranky Kitten, I've had implanon out in August this year and was told by my doctor that i could get pregnant the very next day. However, so far no BFP for me either. I have found out though that I have LP of only 8/9 days - though was told this has nothing to do with implanon.

For me AF has been regular since implanon was removed - odd since it never was before I had it and like you i never had regular periods with it in.

Good luck.
