May I please ask the Rav a Sha’aila?
I counted Sefirah with a Beracha and realized just after I counted that I counted 25 instead of 27 – I did not speak and then corrected it by counting 27. Can I continue counting with a Beracha for the rest of Sefirah? (It is because I forgot to check off the two countings from Shabbos night and Motzei Shabbos).
As long as you corrected yourself and counted the correct day, you may continue counting with a brochoh.
