The cell is not fully fertilized in one flashing instant. The sperm must wiggle into the egg. The wiggle takes a bit of time. Once in the fertilization can commence but it’s not a flashing instant. It takes time. Before fertilization there is one egg and one sperm. After the sperm gets inside and the fertilization is complete there is one fertilized cell. A fertilized cell is not a baby as Rand Paul and some other people who are wrong about conception would have us believe. A fertilized cell takes approximately 30 hours from the time of fertilization, a fusion of the pronuclei and immediate mitotic division to produce two 2n diploid daughter cells called blastomeres. The two fertilized cells are as far from being a baby as can be. Repeat: It takes about 30 hours to produce two fertilized cells. A fertilized cell is not a baby and it’s un-scientific to believe or accept that thirty hours after fertilization there is a baby. There are only two cells. A baby needs far more than two cells.
Your baby when you’re 4 weeks pregnant
From the moment of conception, the fertilised egg – called a blastocyst – starts dividing itself. By the end of this week, it’s a ball of about 200 cells and is about 4-5 mm across. Inside the ball, three layers are forming:
The ectoderm – this becomes your baby’s nervous system, brain, hair and skin.It is not your baby’s nervous system. It is not your baby’s hair or skin. That’s after a week which also proves a baby is not formed at conception.
The endoderm – this becomes the gut and other internal organs.
The mesoderm – this develops into the skeleton, blood systems and muscles.
The outside of the blastocyst divides into two parts:
The outside part sends out little tentacles – called chorionic villi – which bury into your endometrium. The chorionic villi develop into the placenta.
The inside part becomes the amniotic sac – the protective bubble filled with fluid where the embryo develops.
In humans, implantation of a fertilized ovum is most likely to occur around nine days after ovulation; however, this can range between six and 12 days….. Up until then the woman is not pregnant. After that she is carrying an implanted fertilized egg. Remember: a fertilized egg is not a baby. During the second week of pregnancy, there’s still no embryo. No embryo, no baby. Four weeks after the beginning of a pregnancy there is still no embryo… Here’s the science: No embryo, no baby. After four weeks! Are you pregnant? Certainly. Are you pregnant with a baby? Certainly not. Will you eventually have a baby is you are four weeks pregnant? We certainly hope so but hope is not a baby. Neither is a four week old fertilized egg.
Almost all organs are completely formed by about 10 weeks after fertilization (which equals 12 weeks of pregnancy). The exceptions are the brain and spinal cord, which continue to form and develop throughout pregnancy. A baby needs a brain and a spinal cord yet at 12 weeks there is no fully formed brain, hence no baby…. No fully formed spinal cord: no baby. There’s a whole lot more about the development of a pregnant woman and the product of fertilization within her but it’s very wrong legally, morally and actually to call what’s been going on a baby and that’s the point of this information. If you are pregnant we want all the best for you including the continued development of your pregnancy into a successful birth. At that point we are certain the result of the fertilization and development is a baby. .
