yes i had implanon inserted in november when i began my period as directed by my dr. had it in for two weeks then removed it. during the 7 day window thing my husband and i were a bit careless and not wanting another child i use a backup (emergency contracteptive). my period has not returned, its late about 7/8 days. before my daughter i had irregular periods and after they became regular. i have no signs or symptoms. im just wondering is this normal? do i take a pregnacy test? will it return ?
