iud & unprotected sex

i had unprotected sex on friday and he came inside me. i have the paraguard but always have a hard time finding my strings. i’ve had my iud for over 2 years now and it wasn’t difficult for me to find them in the first few months but the longer i’ve had it the harder they are to find. i know they can sometimes soften and curl but i still worry since i can only feel them normally a week before i start my period and that has been touchy. do you think i’m in the clear?
