Honestly, IUD insertion pain varies talaga, some of my mum friends said they felt okay after a few days, while iba naman needed a week or two para maging comfortable ulit. Mas magsuffer ka usually during insertion itself, pero after that it's more about cramping and spotting na talagang maglalast ng weeks habang nag-adjust ang uterus sa device, kaya normal lang if uncomfortable ka pa for a bit. Best to follow up with your OB agad kung ang pain is getting worse instead of better, kasi bawat body is different and doc can check if something's off. Dami naming pinag-usapan ng iba during coffee kasi lahat kami may different experiences, pero all of us eventually got used to it!
