Help!! IUD emergency

Esme • 29 💗 Occupational Therapist🤸🏻‍♀️🎨🌸
Hi everyone, I got Mirena inserted a week ago and at first I could feel the strings. However, for the past 4 days or so, I haven't been able to feel them. I haven't had any abdominal pain or migraines or anything like that. Should I be concerned that the IUD may have strayed? Or could it be that my cervix is just farther back during this time? Any help would be appreciated 😞
