Eh, congrats on getting it done! So normally IUCD shouldn't cause sakit during hubungan intim, if it's positioned properly, you and your partner won't feel it. But honestly, tiap orang lain experience dia, some of my friends said the first few weeks ada slight cramping or mild discomfort, especially if the threads are still a bit poke-y, and it settles down once everything settles in place.
