Anything is better than nothing at this point. If you have no brake fluid you have no brakes, except for the rear parking/emergency brake.
And if the fluid is that low, you'll have to find the leak, fix it and then flush and replace all the fluid anyway, so I would worry more about getting the fluid topped up (DOT3 will work) and then get the 'right' fluid later.
