Periods !!

Ka

I’m wondering if anyone is in the same boat as me or can shed some light please. I’m almost 7 months pp and have been exclusively breastfeeding but yesterday started swapping one breast feed for formula. It went well so today I will swap two feeds for formula. I still haven’t had my period yet and I have the implant in. Do you think it will come sooner rather than later. Or do you think it might take a while due to the implant? Thank you x
