Normally ovulation is estimated to occur 14 days beforethe first day of the succeeding cycle. After ovulation, ovum waits fertilisation not more than 24hours. If not fetilised, it degenerates in the fallopian tube without leaving any trace of it.
Not all ovulated eggs end up in the peritoneal cavity due to the presence of the fimbriae in the fallopian tubes. The fimbriae help in capturing the egg released from the ovary and guide it into the fallopian tube for fertilization. If the egg is not captured by the fimbriae, it may not reach the peritoneal cavity.
The human ovum can remain viable for about 48 hours. And sperm about 24 hours.
An egg moves from the ovary to the uterus, through the Fallopian tubes.
Fertilization requires a large number of sperm to ensure that at least one sperm reaches and successfully penetrates the egg for fertilization to occur. Sperm face numerous obstacles in the female reproductive tract, such as acidic environment and physical barriers, so a large number of sperm increases the chance of successful fertilization. Additionally, competition among sperm ensures that only the healthiest and most viable sperm reaches the egg.
Fertilization of the ovum typically occurs in the fallopian tube, not long after ovulation. The sperm meets the egg in the fallopian tube, and fertilization usually takes place there before the fertilized egg then travels to the uterus for implantation.
The ovulated egg is stopped at metaphase II of meiosis. At this stage, the egg is arrested until fertilization occurs.
Within five days after ejaculation, sperm will typically survive in the female reproductive tract, awaiting fertilization of the egg. The released egg will be viable for fertilization for about 12-24 hours after ovulation. If fertilization does not occur, the egg will be reabsorbed by the body.
From the moment of the fertilization of the egg by the sperm the new baby is alive. However at this stage it is not viable (it can not develop outside the mothers womb).

Once the egg is fertilized it remains fertilized until the egg is eaten, incubated or goes rotten and decays. It never goes back to being an unfertilized egg.
The human ovum can remain viable for about 48 hours. And sperm about 24 hours.
Fertilization of an egg happens before it is laid.
No. By the time a woman is due to menstruate the egg released earlier in her cycle is long dead - typically ovulation occurs 14 days before menstruation, and at most there will only be a viable egg for up to 48 hours after ovulation.
Conception is the moment of fertilization.
