Weigh- in accuracy

Callina • Expecting Baby #1 September 2019💛

i got on the scale and it said i weighed 203. I got on again and it said 199.4 I got on again and it said 199.4 again. So for like 3 times it said 199.4 and only once 203. Do you think my real weight is 203 or 199.4? I weighed with no clothes on in both situations, the first weigh in was just higher for some reason. Also do you think its time for a new scale?
