can hypothyroidism decrease my chances of getting pregnant in the future?

i’m only eighteen and no i’m not trying to get pregnant right now but i do want kids in the far away future and i have hypothyroidism. a nurse told me the other day that it can decrease the chances becoming pregnant. is this true?

i really don’t need people telling me i’m too young to have kids or other rude stuff because as i’ve already said i want kids IN THE FUTURE.

thanks in advance.
