Want this question answered?
A tubal pregnancy is a pregnancy in which the fertilized egg implants itself somewhere besides the uterine lining and the fetus cannot survive.
The fertilized egg (which develops into a baby eventually) implants itself into the uterine wall/lining. The lining surrounds the egg as it matures and develops into a fetus and a placenta and amniotic sac surrounds the fetus eventually to nourish it.
The answer to your question is a zygote. From there, it develops to an embryo and a foetus. Happy science!!!
It is when the fertilised egg implants itself in the lining of the uterus
In humans, eggs are typically fertilized in the Fallopian tube. The fertilized egg begins to divide and continues down the tube and implants in the uterine lining. If it implants in the Fallopian tube, this is known as an ectopic pregnancy (bad). In a chicken also, the egg is fertilized in the first part of the hens oviduct.

The fertilized egg is implanted into the uterine lining.
It embeds itself in the uterine lining, and if it is fertilized, it will stay there for the pregnancy term.
You are probably thinking of an ectopic pregnancy. An ectopic pregnancy, also known as a tubal pregnancy, occurs when the fertilized egg implants itself on the outside of the uterine lining and the baby cannot survive because there is nothing to nurture and provide nutrients to the baby.
When a sperm cell penetrates an egg, and then implants itself in the lining of the uterus, a woman is considered pregnant.
if it is fertilized by sperm it becomes a zygote that embeds itself into the lining on uterus The placenta, which is especially prepared for this event once a month if it is not fertilized it breaks down after a couple of days which signals for the uterus to dispose of the lining in what is seen as menstrual bleeding.
Fertilization would be when conception occurs, if the fertilized egg implants itself in the uterus lining this is when pregnancy occurs and thus the menstrual cycles stop. Although fertilization doesn't always result in pregnancy, and pregnancy can miscarry at any point.
