Welcome to the forum Maisied.
With only 2 goldfish in a 35 gallon tank, you have very appropriate stocking levels. If you cannot afford proper test kits, a simple 30% weekly water change should keep your fish healthy until the filter can cycle. Don't forget to properly dechlorinate the new water before you add it. Some degree of cloudiness is not at all unusual in a new tank. It is a result of bacteria, the free floating kind, reproducing in your tank. Usually it clears up on its own but the water changes should help out a bit.
