Thanks for your query,
These seems to be the common harmone withdrawl symptoms. Apart from it other symptoms which can occur after harmone withdrawl are bloating
in abdomen, PMS etc. Irregular periods
and amenorrhoea are common side effects with implanon
implant. I will suggest you to go for a pregnancy
test just for extra precaution and then proceed ahead with new implanon if you want.
Take care and best of luck..
Hope it helps..
