The number of weeks a pregnant woman has to work depends on her physical condition and the content of her work, and there is no exact standard. If a pregnant woman is healthy, does not have any pregnancy diseases, and has a relatively easy job with little pressure, she can work until the 38th week of pregnancy or even beyond. If the pregnant woman’s body is burdened during pregnancy and she has a pre-eclampsia, pre-eclampsia, or pregnancy diseases such as hypertensive disorders of pregnancy or placenta praevia, going to work will aggravate her condition, and she will need to take a leave of absence in a timely manner, and she can take a break until after the delivery. If the intensity of work at work is very high and the pressure of work is very heavy, going to work will seriously affect the health of pregnant women, pregnant women should also consider stopping going to work in a timely manner and waiting for their bodies to recover after delivery before going to work again.
