In Maariv last night you made 4 brachos on krias shema + 19 in the Amida – 23
Havdalah – 4 brachos – 27
Melava Malka (assuming you washed) – netilas yadayim, hamotzi, bentching – 6 brachos – 33
hamapil – 34
Three weeks from today, it will be more of an issue. We shall subtract three brachos from Havdalah (aish is still used) and the six brachos of melava Malka.
Neverthelss, one can still fulfill his obligation in other ways, such as through saying asher yatzar or saying Amen to other people’s brachos.
Well, the Mishna Berura defines what is considered a bracha for our purposes.
A bracha, generally speaking, requires Sheim umalchus (there are exceptions, such as Elokai Neshama where the Malchus is implied rather than explicit, and it is “appended” to asher yatzar).
