Implant and period

Gals with the implant, if I’m going to start spotting for a long period of time when do you think this would start? I’ve had the implant for a month and got it a week before my period and I pretty much had my normal period but was very light and lasted a week when usually it’s 5/6 days. Is there a change the long spotting could start with my next period or does it seem lkke I’m a lucky one who might not have this?
