The uterus grow to make room for the fetus. A fetus that doesn't grow - no growth of the uterus.
Sometimes fetus is genetically abnormal and dies. Sometimes there is knot in the umbilical cord leading to less blood supply to fetus and then fetus dies. Some times there is partial separation of placenta and blood supply to fetus is hampered. And then fetus dies.
When it dies.
I think it dies
If you die when you are pregnant, an attempt will be made to save the live of the fetus, but, most of the time when the mother carrying the fetus dies, the baby inside of her dies as well.
No.
Yes, it must be surgically removed.
If the child is young enough when it dies, the fetus is simply absorbed. If the child is well developed, medical attention is necessary, as the decaying body can be toxic to both the mother and the unborn sibling. In any case, if you are aware of the death of a fetus that you are carrying, you need to consult a medical professional immediately.
If the mother is not carefull it's possible that the baby dies in her uterus.
it is a huge pancake with a lot of golden syrup on top XD
Plant's growth will be affected
If there is no risk to the other baby, then you can go to full term, or even premature labor. The fetus will have past on and eventually deminimize.
Yes the fetus has to come out and then the belly goes back. You can't go back to be thin again if you have a fetus inside and fluid.
