No. But you can get two eggs fertilized at the same time.
No. If the fertilized egg implants, no period will occur.
The egg cell is called a zygote once it has been fertilized.
The fertilized egg implants and develops in the uterus.
Zygote
Sperm undergo a process called capacitation where they become more mobile and gain the ability to penetrate the egg. Once capacitated, sperm approach the egg and release enzymes that help break down the egg's outer layer, allowing a single sperm to penetrate and fertilize it. After fertilization, the egg undergoes changes that prevent other sperm from entering.
If the egg was fertilized and more than a clump of stem cells in the physical development portion, then yes you could.
A fertilized egg before it implants in the uterus is called a zygote. Once it implants in the uterus, it is referred to as a blastocyst.
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.
Once a follicle releases an egg (ovulation), the egg will travel down the fallopian tube towards the uterus. If fertilized by a sperm during this journey, it may implant in the uterus and develop into a pregnancy. If not fertilized, the egg will disintegrate and be shed during menstruation.
Egg is a female ova (female gamete) which once fertilized becomes a fertilized egg.Each fertilized egg has an external protective membrane( hard shell in oviparous). Often two female gametes get fertilized and have a common protective membrane (hard shell in oviparous).This is why sometimes(rarely) an egg has two yolks inside.
An egg cell is normally released once a month from the ovary. If an egg cell is released and not fertilized, it stops developing and dissolves.
A fertilized egg is known as a zygote. Once fertilized the egg travels down the fallopian tubes to implant in the uterus, this takes around ten days and it's not until this point that a woman is considered to be pregnant. The zygote develops into an embryo, fetus, and then into a baby.
