Where is my antifreeze going if no leak?

I have a 2002 ford focus zts that i have to add antifreeze to every week or two. Its not going into the engine, changed the oil and it was clean oil… Not leaking from exhaust pipe, not leaking from anywhere. Thermostat has already been changed… Where is it going

Added (1). I looked at everything, no smell in car, no wet spots on carpet, outside of car does smell like antifreeze after running for awhile. Oil is cleaner than ever, no bubbles.

Added (2). I think i'll go have a pressure test done

When you have an inexpensive *cooling system pressure test you'll find the source of the external or internal cooling system leaks. If an internal leak is found a cylinder leak-down test will show exactly where the internal leak is found.

Not all internal cooling system leaks go into the crankcase.

You may never see milky oil. Many times with minor gasket leaks, a small bit of water is drawn in on the intake stroke, and all the coolant is expelled during the exhaust stroke. Since you have to top it off once a week or so, the leak is very small. Pressure is probably building up in your coolant system.

Most likely the heater core is leaking under the carpet. Do you have a "sweet" smell in the car's interior?

If we have no external leak? Then it must be ingesting it. This suggest a possible gasket issue e.g. Inlet.
have we checked for antifreeze staining? E.g. Under water pump? In car? Is carpet damp? How much are we adding?

Anti-freeze either gets out on the windscreen or in the oil. The reason its disappearing is because it's being used- how did you think it worked?

Check your oil dipstick and see if it has bubbles on. If so then you probably have a leaking head gasket letting coolant into the crankcase.
