If you’re pregnant, you can have it if the conditions allow, because the main components of the pill are estrogen and progestin, which mainly inhibit ovulation and interfere with the fertilization of the egg, since it does not play a role, generally will not affect the fertilized egg. After pregnancy, you can do more tests, as long as everything is normal, such as Down’s syndrome screening at about 16 weeks of pregnancy, and 4D ultrasound at about 28 weeks of pregnancy, which means that the fetus is not affected. What you need to pay attention to in early pregnancy is folic acid supplementation, which is taken until the second trimester of pregnancy to prevent fetal neural tube diseases. After the third month of pregnancy, the fetus’ neural tube has been developed and the medication can be stopped at that time.
