Hello dear
Understand your concern.
Implanon is type of long-acting reversible
contraception, the most effective form of birth control.
It inhibits the ovulation and
implantation..
Common side effects of implanon are below:
Irregular bleeding and spotting: Delayed period, dysmenorrhoea
weight gain
Ovarian cysts
Acne
So I think it may be withdrawal side effects.
It will take 6-10 week to become regular in some case.
It is generally due to
hormonal imabalnce and body try to accomodate without implanon
If not resolved
You can consult the gynecologist:
Do the full hormonal profile like E2, FSH, LH, pogesterone,
HCG,
Prolactin,
Thyroid profile.
If necessary
endometrial biopsy, follicle study and USG.
Hope this may help you.
Best regards
Dr. Sagar
