When it decomposes you will get severe infections which will lead to blood poisoning and in the end can kill you.
The dead fetus will start to decompose like everything else that is dead and if not removed you will get a serious infection, blood poisoning and become sterile and can even die.
you dead and get sick
The deceased fetus will need to be removed before they send the woman home.
No, a sac grows to accommodate the fetus and if the fetus us dead it does not grow anymore.
The fetus can not grow there and has to be removed.
Some fetus' need to be removed, but most will come out (if before 12 weeks) usually after 12 weeks it will be removed, it is very dangerous that the fetus is still in the mother, this can cause blood poisoning which can lead to death of the mother if not treated fast. Although, in rare cases fetuses have been known to remain for years and even decades.
The fetus is generally already dead when the miscarriage occurs.
The soil will no longer be healthy for plants
the placenta
Delicious ;)
Eventually she will get serious infections since the fetus will decompose inside of her. That will spread and get into her bloodstream and finally kill her unless she gets treatment and the fetus removed. It would be very painful. If you suspect you are having a miscarriage you have to see a doctor and also if you don't suspect it you have to go to regular checkups to make sure everything is normal.
Usually not. A fibroid should be a round mass in the wall of the uterus. A dead fetus would not be round and would be in the uterine cavity.
