I thought it was effective up to 5 years then found out it was 3 just then. 2 months out of date. Still having regular periods. Last one 3 weeks ago. Very annoyed I believed it was 5 years.
Spent the night researching. Conflicting information on the internet. Studies done where 'off label' implanon is effect till 4 years then articles where women have gotten pregnant before the 3 year date.
Will see doctor first thing in the morning. Very worried.
