Ehhh normal lah tu actually, hormones tu kena juggling time awal-awal depo jadi period boleh jadi unpredictable, ada yg skip, ada yg heavy, ada pulak yg bleeding lama macam cerita ko ni! A few of my mum friends yang cucuk depo pun ada yang experienced similar thing, so don't worry sangat lah, usually settle down after 2-3 bulan. But kalau period ko lama sangat or ada other symptoms yang buat ko concerned, better check with your doc just to be sure everything's ok ye?
