Thanks for the query.
After removal of implanon
it may take sometime for regularization of the periods.
The bleeding you got after 2 weeks could be withdrawal bleeding due to removal of the implanon.
The spotting now you are having can be ovulatory bleeding.
So you better wait for December 8th, if you miss the periods go for pregnancy
test once. If the test comes negative this time track the ovulation with kit and plan intercourse around that period.
