How do i make sure my iud mirena is in the right spot?

i got my mirena inserted August of 2008. i got a check up cuz i was worried. its weird to just have and not worry about getting pregnant its so good 2b tru thats y im always wondering. so how can i check it myself. oh yeah back to the doctors check up. i gone 2ice since i got it inserted she tells me its fine so i went to a guy gynecologist n he says its fine too.. the thing 4me is they tell me to check while on my period and afterward.. i just never feel nothing! i know its deep inside there cuz they both had a hard time finding it. so it would be cool if anyone who has gotten pregnant while on mirena can explain how it felt..i mean i feel normal i still have regular periods. i just want to know when should i worry.. my gynecologist told me to not to worry only get it checked once a yr IF i feel its out of place. so since i just CANT reach does that mean its good cuz its safe right? or do i just have small hands and to b honest i rather not check it myself im 2paranoid that if i touch it i'll think i messed it up! lol. and stupid mirenas website should have info on this. its their freakin product! they should give us ll the details!
