Possible sign of bad head gasket?

[Ceauxkneauxs00]

I’ve had to add coolant twice in 2 months. Due to it being winter time it’s difficult to see if there’s anything on the ground after it’s been sitting. Just hoping it’s something less expensive than replacing the head gasket.

head gasket will cause the oil to look similar to a milk-shake. Disappearing coolant could be heater core but you will usually smell it

Would I check the dipstick? What type of smell? The smell would be bad heater core or gasket?
