You can wear makeup during pregnancy preparation, but for the sake of eugenics, it is recommended to wear light makeup, try to choose natural cosmetics, do not use cosmetics that contain a lot of chemicals, and do not wear heavy makeup, as light makeup will not affect the quality of eggs. In addition, you should be careful not to dye or perm your hair during pregnancy preparation, as hair dyes and perms contain many chemical ingredients that affect the quality of sperm and eggs, so it is inappropriate to dye your hair or do your nails during pregnancy preparation. It is important to maintain a good state of mind during pregnancy preparation and not to be overly stressed, as excessive emotional stress can also affect the probability of pregnancy. You can carry out normal daily activities, take appropriate physical exercise, and get enough sleep and rest to enhance your physical fitness, which will help to increase the probability of pregnancy.
