Questions???

Jaylen • I am 22 and a mommy to one beautiful baby girl born on February 20th 2014.
So I was on the implanon implant for about 5 months and had it removed in September due to constant bleeding. Now since having it removed I spot for an hour or so one day of the month but haven't had an actual period. There's no way I'm pregnant because we have been using condoms . Just wondering if this is normal or if anyone else has had this problem.
