I breastfed for 6 months and still didn't get my period still my son was 1
Google says a lot of different things, from 5-6 weeks for non breastfeeding mums to 3 months, I think it’s dependent on your body, I’m 8 weeks pp and still have had nothing yet :)
maybe contact your GP if your really worried. i haven’t had a proper period since but i do exclusively breastfeed so i guess it’s different.
