Taking the emergency contraceptive pill can easily cause ectopic pregnancy if you get pregnant, which means that the incidence of ectopic pregnancy is significantly higher. Therefore, a vaginal ultrasound can be performed at 35-40 days of pregnancy, and if the gestational sac can be seen in the uterine cavity, an ectopic pregnancy can be ruled out. If the pregnancy is normal and the fetal heart and germ are well developed, taking the emergency contraceptive pill will not have a great impact on the development of the fetus. It is well documented that the emergency contraceptive pill does not increase the likelihood of abnormalities in the pregnancy or the fetus, so if you have the desire to have a child, you can have the child. However, if you don’t want to have a baby, you can choose to have an abortion between 40 and 70 days of pregnancy, when the abortion will cause the least damage to your body.
