It depends on what instrument you are measuring your weight. If you are measuring the mass with a beam balance then your mass will be same as your actual mass provided you have taken the observation accurately.

However, if you measure it with a spring balance, which is dependent upon the gravitational pull of earth, your mass may vary as gravitational force on earth varies with place to place.

In equator your mass will show lesser than 42 kg and in poles it will show more than 42kg, if you measure the mass using a spring balance.
