If you are really worried about the development and health of the fetus, you can go to the hospital for ultrasound and blood HCG tests to determine whether the fetus has abnormal development and whether the blood HCG value is normally elevated. Since the components of the drug are easily transmitted to the fetus through the mother, they may affect the fetus. Therefore, if an unplanned pregnancy is detected during the nine-valent vaccination, it is recommended to postpone or interrupt the vaccination process and continue the vaccination after the delivery and breastfeeding period, noting that it is not necessary to start the vaccination from the beginning. If you have not taken folic acid to prepare for pregnancy normally, you need to keep taking folic acid until the third month of pregnancy after finding out you are pregnant. During pregnancy, especially in the first 3 months, you should avoid strenuous exercise, do not catch a cold, do not eat spicy and stimulating, too cold or too hot food, which can easily lead to gastrointestinal discomfort. At the same time, you should not take any medicine, and alcohol and smoking should be prohibited. In addition, if you have no plans to have children, you can choose to terminate your pregnancy. After termination of pregnancy, it should be noted that a period of time should be allowed before continuing the nine-valent vaccination. If the vaccination is given when the uterus is not fully recovered, it will be detrimental to the recovery of the uterus. The vaccination should be administered after the uterus has recovered completely. It is important to note that no matter which type of abortion is performed, it will have adverse effects on the body and should be performed in a regular hospital. After the abortion, it is necessary to rest in bed, strengthen nutrition, and use anti-inflammatory drugs reasonably to prevent infection and promote body recovery. If you have no plans to have children, you should take good contraceptive measures.
