Hey KMH, i had implanon for 4 years and what it does s put your boduy in a pregnant like state - it uses a sinthetic hormone similar to progestrone that stops your period ...

I wouldnt worry to much i would sometimes have no period for 12 months then get them 3 times in 2 months for 2 weeks ata time... it is the downside of the contraception... and alot of women get it removed for that reason....

some women spot blood some have heavy periods for prolonged periods of time some dont get any period for the whole 3 years....
