I stayed in a newly renovated hotel several times during my pregnancy. What if there is formaldehyde?

If pregnant women wait for a long time in a room containing formaldehyde, it will aggravate the pregnancy reaction, and nausea and vomiting will be more serious. The incidence of pregnancy poisoning, anemia and threatened abortion will increase, and at the same time, it will also lead to gene mutation, which will eventually lead to birth defects such as fetal developmental malformation, abortion, fetal brain development damage and congenital heart disease. Therefore, pregnant women should not live in newly renovated rooms, especially in the first three months of pregnancy.
