This might be..a VERY stupid question

li

So after I got my IUD my doctor told me no sex, baths or tampons for 2 weeks. He cut my cervix so that makes sense.

BUT he said after 2 weeks I need to use condoms until my 1 month check up to see if the IUD is in the right place.

So my dumbass got to thinking... can IUD strings rip a condom open? We plan to use the ultra thin ones but maybe I should rethink that
