Eh depends la on whether you're breastfeeding or not, a few of us tried mixed feeding and period came back around 3-4 months, tapi those who exclusively breastfed, theirs took longer, around 6 months or more! Kalau formula feeding, biasanya lebih cepat, sometimes just 6-8 weeks je. Siapa tahu though, every body is different, so don't be shocked if yours datang earlier or later than expected!
