The fetus also urinates in the womb and swallows its own urine. Especially in the third trimester, the fetal urine is basically the main source of amniotic fluid. The fetus will swallow the amniotic fluid and then discharge it to maintain the balance of the amniotic fluid.
So each of us actually grew up drinking his own urine during the fetal period. Maybe when it comes to this, some people will feel sick. In fact, the fetal urine is not as dirty as we think, it is free of bacteria and does not pollute the environment of the uterus, so pregnant women do not have to worry.
As for bowel movements, in the early stages of pregnancy, the fetus’ defecation ability is actually very weak, and only a small amount of feces will be discharged into the amniotic fluid. The feces that are discharged will also be handled by themselves, and some will be handled by the pregnant mother.
