You pull the line first. If it hurts, you can wait another two days. If not, you can just unplug it. The same is true for taking the thread in the hospital. You can pull it out directly with tweezers.
I pulled it out directly on 14.5, and some of it didn't hurt, so it was easy to pull it out. One needle hurts a little, and the thread is not absorbed at all. It's completely pulled out, and there is still some blood. It will be fine the next day. Try it. Just pull out the iodophor.
