Salam! Keluar darah sikit after depo injection memang boleh jadi normal, tapi sebab ni first time you cucuk, lebih baik check with your doctor or nurse je to be sure, especially kalau banyak atau lama sangat. A few of my mum friends had some spotting after their first depo, tapi each person berbeza. Depo memang boleh affect your cycle in the first few months, jadi jangan worry sangat dulu la, but do get it checked just to be safe, ya?
