Some of them will have abdominal pain at the beginning of pregnancy, and some of them will not feel anything. Due to the stimulation of the bones caused by the increase of the uterus, pregnant women feel a vague pulling pain in the small abdomen, which will be fine when they rest slowly. If there is obvious abdominal pain and vaginal bleeding, it is necessary to consider the possibility of miscarriage. If there is abdominal pain without vaginal bleeding, it is necessary to go to the hospital for ultrasound examination to see the development of the fetus and progesterone test, and it is necessary to take immediate bed rest and apply fetus preservation drugs. If your stomach is in pain and you have a feeling of falling, consider the possibility of ectopic pregnancy, as it is normal to have mild pain during pregnancy. If the pain is more severe, go to the hospital for an ultrasound examination in time to prevent the condition from worsening or miscarriage, most commonly ectopic pregnancy.
