How the heck do I check....

How do I check for the iud!? 
I have no idea where my cervix even is lol I have tried feeling up there and I can feel the strings for the thing but the dr told me I need to go all the way to my cervix to make sure it is not falling out. I felt what I thought was my cervix the other day but it wasn't straight up...almost as it it was on one of the sides. Ugh, I hate this iud.
