Whether or not you can continue the pregnancy if you are pregnant from smoking, you need to go to the hospital for ultrasound and other relevant examinations to determine the development of the embryo, and then decide whether or not to terminate the pregnancy. Cigarettes contain nicotine and other substances that are not good for the human body and have a great impact on the fetus, so it is necessary to know the development of the embryo first. If the test reveals that the embryo is not developing well, the pregnancy should be terminated promptly. If the embryo is found to be developing OK, the pregnancy can usually be continued, followed by regular pregnancy tests. It is recommended that the mother quit smoking immediately after the pregnancy is detected, and family members are also advised to quit smoking as much as possible, so that the harmful substances in tobacco are not passed through the bloodstream and through the placenta to the fetus, leading to developmental malformations and other problems.
