Q. There are those whose family Minhag restricts their female members from reciting a Bracha on Sefiras HaOmer lest they miss at least one day.
Suppose one of them does count every night of the first 48 nights. Can she count the last night with a Bracha since after the 49th night there are no more days in the counting to miss?

A. Although, for a woman being stringent and not reciting a brocho when counting sefira should not be considered a neder shel mitzva, still Horav Shlomo Miller’s Shlit”a opinion is that it is better not to recite a brocho even on the last day.
