Hai babe, spotting coklat tu quite normal lah dengan depo, especially dalam bulan-bulan pertama, hormon tu kena time to settle dalam badan. A few of my mum friends juga kena spotting on and off after their injection, so you're not alone! Tapi kalau it's heavy bleeding atau dah berjalan lama sangat, better check with your doctor just to be sure everything's okay, ya?
