If you take a lot of drugs without knowing that you are pregnant, whether it will affect the fetus or not, clinically it is important to know which kind of drugs you have taken. There are some drugs that will not affect the fetus, like cefuroxime, which will not affect the fetus, and macrolides, which will not affect the fetus either. However, if oxyfloxacin or fluconazole or haloperidol are taken, such antibiotics can clinically lead to the possibility of fetal developmental malformations, so they must be treated with caution, and some of them may cause symptoms of preterm abortion such as vaginal bleeding and lower abdominal pain after being taken. It is advisable to bring the medication to the eugenics clinic of the hospital for further consultation, so that the doctor can understand whether the medication will affect the fetus and then decide whether to terminate the pregnancy.
