Patients need to pay attention to the following aspects during pregnancy preparation: First, be sure to take folic acid supplements during pregnancy preparation. During the 3 months before conception and the 3 months of pregnancy preparation, you must take 0.4mg of folic acid every day, which can well prevent fetal neural tube malformation. Secondly, patients must protect themselves during pregnancy preparation and try not to get sick or catch a cold. In case of illness, make sure to inform your physician that you are preparing for pregnancy. Choose drugs that have little or no effect on the development of the embryo. Thirdly, patients must pay attention to their diet, do not eat spicy food, eat less seafood and other hairy products, and eat more nutritious food or light food. At the same time, you must not stay up late and have a more regular lifestyle. Fourth, the patient must relax during the preparation for pregnancy. It is especially easy to affect the patient’s pregnancy because of nervousness. Patients can divert their attention or listen to music, take more walks, chat with friends, and do not take pregnancy preparation as a burden.
