Kyleena strings

So I just got my kyleena IUD today and just out of curiosity I was going to see if I could feel my strings. I was kinda squatting over the toilet (like you would with a tampon” and my strings are so low they are at the opening of my vagina. I thought maybe it was the position I was in so I checked it laying down and my strings are still very low maybe only a inch from the opening. Should I be concerned it fell out? My doctor didn’t say anything about the string softening over time nor how long they should be. I’m going to call in the morning to see if I should come in but I was wondering if this happened to anyone else?
