Tłumaczenie - Portugalski brazylijski-Angielski - No fim tudo dá certo, se ainda não deu, é porque...

in the end, not at the end...

Everything will work out fine in the end, if it hasn't yet it is because it hasn't ended yet.

because it still has not reached its end

I chose meaning correct, because the meaning is contained in the translation, but I second the suggestion "Everything will work out fine in the end" as a better way of writing this in English.
