Sis, a few of us in my group tried IUD after breastfeeding, and honestly ramai yang kena heavier periods and cramping for the first few months, but it settled down for most, so don't worry too much. Timing-wise, some mums suggested waiting a bit if you're still recovering postpartum or just stressed, sebab stress buat symptoms terasa lagi heavy, tapi majority said just go ahead when you're mentally ready. Best talk to your gynae about your specific situation la, they can advise based on your health history and timing that works best for you, especially if you're worried about side effects or when to slot it in between raya. Rosaknya apa? Kontraception ke for spacing?
