Please bear in mind that we begin to say ??? ?? ?????this evening (Wednesday evening).
What if you don't remember whether or not you said ??? ?? ????? The rule is that you?have to assume that by force of habit you probably didn't say it, unless thirty days of saying ??? ?? ????? have passed so that its recitation has become habitual.
What should you do if you?didn't say ??? ?? ???? ?????? All is not lost:
If you remember before saying Hashem's name at the end of the brocho (???? ??? ???) then you simply backtrack to ??? ?? ???? ????? and finish the brocho properly.?
If you already said ???? ??? ??? at the end of the brocho, you can still salvage the situation by saying ??? ?? ???? ????? in ??? ?????? (before ?? ??? ????...).
What if you forgot to insert ??? ?? ???? ????? even in ??? ??????? Here it gets complicated:
If you haven't yet said ???? ??? ?, just backtrack a little and say ??? ?? ???? ????? ?? ??? ???? ????? ??? etc.
If you said ???? ??? ???, but no more, you can turn the words ???? ??? ??? into a ???? by adding ????? ?????; that way you still haven't finished the ???? and you can go back the few words and say ??? ?? ???? ????? ?? ??? etc., as above.
But if you went even one word further and said ????, or ???? ?????, then you can't backtrack. But there is still one more opportunity. If you haven't yet begun ??? you can say ??? ?? ???? ????? right there in the space between the two ??????(??? ?????? and ???) and it's considered part of ??? ??????.
But if you began ??? already, then you have to go all the way back to ??? ?????.
And if you finished ????? ???? entirely - or even just said the ???? ????? ???? ?? at the end of ???? ???? - then you have to say the whole ????? ???? again. (And try not to forget it again this time, or you could be davening all day.)
