Fetal development means a fertilized egg is already in the process of becoming a baby. The question is asking "How does the body ensure that only one pregnancy is occuring at a time?"

Luteinizing Hormone is produced and released by the pituitary gland and it triggers ovulation. When pregnancy occurs, LH levels are decreased to prevent ovulation and  a (second) pregnancy. (No new egg = no new fertilization)

Very helpful if the body is already developing a baby!
