Ade je mommies yang pakai IUD tapi still period, especially dalam first few months after insertion, it's totally normal! Some of us period jadi heavier or more irregular dulu, tapi usually settle down after a few cycles. If you're thinking about IUD, do check with your gynae about which type suits you best, sebab some types (like the hormonal ones) actually lighten your period over time. Mana one you're considering? Ada pros and cons each type!
