If you are pregnant on the 40th day of pregnancy and have taken medicines to activate blood circulation and remove blood stasis, you should consult a doctor in time, closely observe the situation of abdominal pain and vaginal bleeding, and follow the doctor’s instructions to carry out fertility preservation or miscarriage treatment according to the results of the examination, etc. Do not judge on your own and blindly use medicines, so as not to cause adverse consequences. The combination of the embryonic sac and the uterine wall is not very stable in early pregnancy, and taking medicines that activate blood circulation and remove blood stasis at this time may lead to bleeding or even miscarriage. Taking drugs in early pregnancy is also likely to lead to fetal malformation. Pregnant women should closely observe their abdominal pain and vaginal bleeding, and promptly go to the hospital for appropriate examinations, such as human chorionic gonadotropin-releasing hormone and gynecological ultrasound. If everything is still within the normal range, you can follow the doctor’s instructions to carry out fertility preservation treatment or temporary observation, if there is an abnormality, you need to follow the doctor’s instructions to carry out fertility preservation or abortion treatment. Pregnant women should consult a doctor in a timely manner, under the guidance of the doctor, actively cooperate with the treatment, and do regular obstetric examination during pregnancy. Pregnant women are advised not to take any medication during pregnancy to avoid adverse consequences.
