Pregnancy Week 1

Pregnancy Week 1

We are counting with the gestational age method, hence week one begins with the first day of menstrual period. Conception hasn’t yet occurred, but a woman already gets to start counting. Period has just started and a woman thinks about conception. For women with a 28 day cycle, ovulation occurs around 14 days after the start of menstrual cycle. Now is a good time to begin healthy habits. Pregnancy diet should start during pregnancy week 1 itself with plenty of fresh fruits and vegetables; exercise; taking additional folic acid if haven’t already; and should stop smoking, drinking alcohol, and using over-the-counter medications. A woman who is pregnant and entered in the pregnancy week 1 should stay away from toxic materials and rest well. She should start “thinking pregnant” before she conceives so that she can give her baby the best start possible.

Development

Approximately 14 days before period is due, an egg (ovum) is released from the body and the lining of the uterus starts to thicken. It only takes one sperm out of millions that make the long journey up the Fallopian tube where the egg gets fertilized and the process of growth and development begins. Approximately 14 days before period is due, an egg (ovum) is released from the body and the lining of the uterus starts to thicken. It only takes one sperm out of millions that make the long journey up the Fallopian tube where the egg gets fertilized and the process of growth and development begins. The cell division begins as soon as the tails separates from the head of the sperm and it penetrates the egg. Within hours, the fertilized egg becomes two cells, then four, then eight and so on, and is called a zygote. A week after fertilization, the ball of cells -now hollow in the centre called a blastocyst -reaches the uterus. The blastocyst will attach itself to the wall of the uterus and begin to embed deep into its lining. This process is called implantation. The cluster of cells very quickly will produce an outer layer, which will develop into the placenta and amniotic sac. The inner layer will develop into the embryo. The outer layer has root-like structures that bury into the lining of the uterus. These become the route by which nutrients and oxygen are transported from the circulation which will soon be the placenta and embryo which keeps developing.

Life is changing!

A woman starts experiencing mood swings and a variety of different emotional changes in the first few weeks. Pregnancy week 1 is a time filled with expectation and anxiety for most couples. A woman.s last period might have started between 12 to 16 days ago and might be ovulating during this time. It is important and essential that a woman during pregnancy week 1 itself starts reducing stress as much as possible as too much stress actually reduces chances of conceiving successfully. A woman should spare time to meditate and also reflect on the joyful aspects of life during first few weeks of pregnancy.

Changes in the body

During pregnancy week 1 incredible number of changes occurs in a woman.s body. Hormone levels change significantly. The uterus creates a rich lining of tissue, which supports the fertilized egg after conception.

Ovaries produce ripe eggs in vessels called follicles. During ovulation, which typically occurs around the 14th day of a menstrual cycle that is 28 days long, one or more of the eggs burst out of follicles. These eggs will then wait patiently in the Fallopian tubes where sperm can fertilize them. It takes roughly about ten hours for sperm to reach the egg.

In the early weeks of pregnancy the sperm’s nucleus commingles with the egg, and the baby’s gender is determined. Sperm carrying a Y chromosome generally results in a baby boy, while sperm carrying an X chromosome generally results in a baby girl.

During pregnancy week 1 and two the fertilized egg, known as a zygote, will divide into multiple cells and start burrowing into the rich lining of the uterus. The baby now is simply a ball of cells that transforms into a blastocyst. The blastocyst consists of an inner cell mass that eventually transforms into the embryo, which is another cavity that becomes the amniotic sac. The outer cell body becomes the placenta. It is absolutely amazing to know how a baby develops from this ball of cells.
