Wa'alaikum assalam! Honestly sakit sikit je, tapi tak la sangat painful, lebih ke uncomfortable feeling je, macam period cramps or pressure. A few of my mum friends dah cabut IUD, semua cakap the actual removal process cepat je, maybe 2-3 minutes, tapi memang ada rasa sakit atau kram-kram sikit masa cabut. Better check with your doctor or clinic sebab setiap orang lain experience, and they can explain exactly what to expect and bagi painkiller kalau kailangan.
