How do I get current week's data from table in Laravel

I am trying to get this current week's data from my table

I have the following code which gives me 31 days of data (A month but it's seperated)

$stats["tmv"] = "";
$stats["tmd"] = "";
$stats["tru"] =  array();

        for ($i=1; $i <= 31; $i++) {
            $stats["tmv"] .= DB::table('stats')->select(DB::raw('*'))->where(DB::raw('DAY(created_at)'), '=', $i)->where('stats_type', "mv")->count();
            $stats["tmd"] .= DB::table('stats')->select(DB::raw('*'))->where(DB::raw('DAY(created_at)'), '=', $i)->where('stats_type', "md")->count();
            $stats["tru"][$i] = DB::table('users')->select(DB::raw('*'))->where(DB::raw('DAY(created_at)'), '=', $i)->count();

            if ($i != 31) {
                $stats["tmv"] .= ",";
                $stats["tmd"] .= ",";
            }
        }

Output: "tmv" => "11,4,1,13,0,5,15,2,0,24,1,7,17,18,45,14,31,61,3,1,4,1,1,27,30,47,18,60,10,0,156"

How do I edit my query to select this current week's data?
