In the case of a fetus that is two weeks on the large side, it will not necessarily be born early, and there will be individual differences that will affect it.
There is no obvious correlation between the size of the fetus and the time of labor initiation. Some fetuses may be large, but labor does not start in the 40th week of pregnancy. Some fetuses may be small, but may be born before 40 weeks.
As you can see, there is not a strong correlation between the weight of the fetus and when labor starts. In the case of large fetus, it may be caused by over-nutrition, so pregnant women should do a good job of balancing their diet and nutrition to avoid the emergence of a huge baby, which will affect the delivery.
Fetus is two weeks large, need to control the appropriate diet, and the time of labor initiation has nothing to do with the size of the fetus.
