Newly pregnant patients should not do strenuous activities, especially those that increase abdominal pressure. This is because in the first trimester of pregnancy, the embryo is still relatively small and has not formed a placenta or has just formed a placenta, which is still particularly unstable. The relationship between the embryonic tissue and the wall of the uterus is not particularly tight, so if you do strenuous activities that increase abdominal pressure, it may cause the patient to have a miscarriage. Therefore, when the patient is newly pregnant, she should not do strenuous activities such as running, jumping rope, climbing mountains, or flying car races or cycling races. The patient can walk, stroll, and do some gentle activities. In addition, patients in the early stages of pregnancy as far as possible not to coitus, do not lift heavy objects, coitus may stimulate the cervix, lifting heavy objects may increase abdominal pressure, may cause miscarriage.
