It would be helpful to provide a replay, because the answer to your questions includes a lot of different factors... the biggest one is the map you play on.
On some maps it's a lot easier to counter earlygame brits as OKW (example: Elst, Lierneux), and on other maps you can do literally nothing in the first 5 minutes (e. g. Crossing in the woods, Road to Kharkov)
