Haah, banyak je mommies kat sini pakai IUD! Few of my mum friends yang pasang, diorang mostly okay je, tapi memang la few weeks pertama ada cramping, spotting, dan heavier periods for some. One of them ada period yg intense gila untuk 2-3 bulan lepas pasang, but settle down after that. Most common la tu, some bleeding, light cramps, macam period pain je, and maybe mild back discomfort kat few days first. Tapi kalau pain tu teruk sangat or ada heavy bleeding sampai nak ganti pad every hour, better check with your doc sebab not everyone's experience is the same, kan. Kita ni lain-lain body!
