If one missed one (complete) day of counting Sefiras Ha’omer (or counted incorrectly i.e. counted the wrong day) one should continue to count each subsequent day, but without a beracha. Shulchan Aruch w/Mishnah Brurah 489:8
However, one should, if possible, hear the beracha said by someone else (and answer Amein) to be able to fulfill the mitzvah properly, with a beracha. Shulchan Aruch w/Mishnah Brurah 489:8
