The smell of pesticides has an effect on pregnant women. Smelling pesticides too much in early pregnancy can have an adverse effect on the embryo, which can easily cause embryonic malformation or even embryonic abortion in serious cases, so avoid exposure to pesticides during pregnancy. However, if you occasionally smell pesticides, the impact on pregnant women is not significant. If you live in such an environment for a long time, the impact on the fetus and the pregnant woman is relatively large. In addition to not being exposed to pesticides, you should also be aware that a newly renovated house may have excessive formaldehyde, which can also have a negative impact on the pregnant woman and the fetus. Pay more attention to breathing fresh air, which is good for the fetus, resting more, not staying up late, strengthening nutrition, eating more seasonal fruits and vegetables, and doing regular maternity checks.
