Paraguard question

Ok, I've had the Paraguard IUD for almost 4 months. Today I was doing a string test to check it, but when I went to check it I felt something hard, opposed to the string. I was in a deep squat when doing this and my finger was pretty high up.  Is it possible that I'm able to touch the tip of my paraguard? Could it possibly be displaced? Could the strings have came off or bunched up and I can't feel them? Please offer opinions and possibly solutions. I'm thinking about going to get it checked out at a doctors office, but I'm not sure if it's necessary if this is a normal thing. Thank you!
