Aduh, I can relate to this worry, honestly. A few of my mum friends went through miscarriage dan memang stress gila nak tunggu period datang balik sebab takut ada something wrong. The thing is, setiap body recover differently, ada yang period balik dalam 2-3 minggu, ada yang ambil bulan lebih, dan there's actually a small chance you bisa pregnant before period comes back. Best la you check with your gynae to make sure everything's healing properly dan get clarity on when it's safe to try again, sebab timing pulak important after loss.
