If a pregnant woman is injured, she can apply a Band-Aid. The purpose of a Band-Aid is to protect the wound from contamination. Generally band-aids do not contain drugs, so they do not affect pregnant women and babies. If a pregnant woman suffers a trauma during pregnancy, she should still go to the hospital to deal with the wound, because if the wound is not handled properly, it can easily lead to wound infection. At the same time, during pregnancy, if pregnant women need to use drugs, it is possible to use under the guidance of a doctor, most of the drugs as long as the regular use, and will not increase the risk of pregnant women and fetuses. So neither should you use medication blindly, nor should you refuse treatment for fear of your baby’s condition. During pregnancy, pregnant women should also pay attention to their personal safety and health, and go to less crowded and more dangerous places.
