If you get pregnant despite taking the pill, you can have the baby, but you need to undergo some eugenics tests. Because the current theory is that the pill does not absolutely increase the risk of teratogenicity, and the pill is mainly used to interfere with the implantation of the pregnant egg, if the interfering egg fails to implant, it is possible to have the baby. Therefore, after pregnancy, some eugenic tests and regular pregnancy tests are very important. After pregnancy, four eugenic tests, liver and kidney function tests, blood glucose and lipid tests, folic acid bioavailability tests, blood type and routine blood tests should be performed. The folic acid should be given orally to prevent the occurrence of fetal neurological malformation and to treat it, and regular pregnancy and delivery checkups should be conducted during pregnancy.
