Welcome to HealthcareMagic forum.
Presuming your cycles were regular in the past before implanon
insertion, the current period of amenorrhea
(absent period) is related to hormonal
changes induced the implant. These changes usually reverse in 2-6months time. Sometimes we use regular combined oral contraceptive pill
briefly for 3-4 months to get the cycles back to normal.
Since you are trying to conceive and periods are yet to happen, I would suggest you to consult a competent gynecologist. He/she can plan a few blood tests like serum FSH levels, ultrasound
scans and put you on regular birth pills.
Hope this helps.
