I had my implanon removed 18th of Feb, Had some spotting on 13th of May, then a "proper" AF on the 14th of April. Fingers crossed this for this cycle. I think I was a 31day cycle before implanon. So long ago I can't remember. I had implanon (2 of them) for about 5 years and 4 months.

Just remember everyone is different, you may fall straight away or it may take a few months, but it may have taken that amount of time without coming off implanon anyway.
