If you have intercourse several times in the first month of pregnancy, if no abnormal symptoms appear, it has little effect on pregnancy. If you have discomfort, seek medical attention in time to check the development of the fetus and intervene for treatment if necessary. If there are no abnormal symptoms such as vaginal bleeding and abdominal pain after intercourse, you can observe first. During the observation period, you should closely observe the changes in your body and seek medical attention immediately if there is any discomfort. If there is vaginal bleeding, abdominal pain and other uncomfortable symptoms, you need to go to a regular hospital immediately for relevant examinations to understand the condition of the fetus. If the symptoms of vaginal bleeding and abdominal pain are mild, you need to take absolute bed rest under the doctor’s guidance, and if necessary, carry out fetal preservation treatment; if the symptoms of vaginal bleeding and abdominal pain are severe and there is no significant improvement after fetal preservation treatment, you may need the doctor’s judgment whether to terminate the pregnancy. The first month of pregnancy belongs to the early stage of pregnancy, when the placenta has just been laid and developed, and other aspects are unstable. In consideration of the health of the fetus, intercourse is not recommended during the first three months of pregnancy. In the early stage of pregnancy, pregnant women should take more rest, do not work too hard and avoid strenuous exercise; take regular supplements of folic acid and folic acid-rich foods, such as spinach, tomatoes and carrots, to prevent fetal neural tube defect malformations.
