After pregnancy, due to the increase of progesterone, the gastrointestinal movement will become slower, so it is easy to have dry stool. If there is hemorrhoid or anal fissure, there may be bleeding when defecating. However, the bleeding must be determined to be anal bleeding. The amount of bleeding is not much, and the color is bright red, attached to the surface of stool. If the bleeding is dark red or there is blood on the underpants, it may be vaginal bleeding. Vaginal bleeding after pregnancy is abnormal. You should go to the hospital in time to have a B-ultrasound examination to see whether the development of the gestational sac is normal and whether there is fetal heart and embryo bud. If it is abnormal, it should be treated in time.
