Thanks for the query.
I understand your concern.
After removing implanon it will take some time for restating of ovulation and menstruation.
The lower abdominal pain and backache you are having at present could be possibly due to impending withdrawal bleeding due to removal of implanon or vaginal infection due to unprotected intercourse.
Now it is difficult to predict the time of ovulation. So, better to wait till your withdrawal bleeding and after that track your ovulation with ovulation kits in the middle of month and plan unprotected intercourse around that period which will increase the possibility of pregnancy.
