The most interesting and fascinating moment in the life of every women is the time when she becomes pregnant. For those who are conceiving a baby for the first time must be a bit tensed because this is an unusual experience in their life. Even the mothers who are becoming pregnant the next time after having a baby, experience the same feelings of joy. Well during pregnancy the fetus takes considerable amount of time (40 weeks) to develop. If you are pregnant then quickly acknowledge the stages of the fetal development that are illustrated below:
4.1STAGES OF PREGNANCY
Pregnancy in 1st Week
This is generally the initiation week of your pregnancy. It is generally counted from the first day of the starting of this 1st week of pregnancy till the end of the 40 weeks. In the 1st week the follicles will bear the ovum and within a few days the fetus will start developing in the womb. You may experience some weakness or any sort of tiredness during this week.
Pregnancy in 2nd Week
This is an important stage of your pregnancy. Your womb becomes completely prepared for the embryo to develop. The inside layer of the womb condenses and the mucus in the cervix gets slender to allow the sperm cells to pass into the fallopian tube. Now it’s the time for your ovulation. The follicles that were carrying the ovum bursts, and this discharges the ovum into the fallopian tube. Once inside the fallopian tube the ovum can survive for a period of 24 hours. Fertilization must occur in this time so as to initiate 2nd week of pregnancy. If it happens that fertilization doesn’t occur due to some reasons during this period, the ovum will get discharged during the next time of your menstruation process. Generally this doesn’t happen when the potent sperm cells are present inside the fallopian tube of a woman’s body. So you don’t need to worry.
Pregnancy in 3rd Week
In this time the fertilization takes place in which the ‘fertile’ spermatozoa will unite with ovum to produce a particular cell. This cell ultimately develops as the baby. This is the 3rd week of pregnancy. By the process of cell multiplication it will develop into hundreds of many cells and they will be transferred through your fallopian tube to the uterus region. The cell multiplies in the order of 2 initially and then it becomes more in number. This passing of the cells to the uterus generally takes 3-4 days.
After the end of the 3-4 days the egg forms with a watery liquid packed in the center region and it gets ready to enter the uterus. The egg is now termed as Blastocyst in medical terms and it is found to have two layers surrounding it. These layers will ultimately develop in to the embryo and the placenta. The Blastocyst will remain in the womb and gets nourishment from the secretion of the glands present in the uterus wall. Just at the end of this week the Blastocyst will eventually affix itself to the wombs inside layer. The process is known as implantation. You are now said to be having a baby as soon as implantation takes place.
Pregnancy in 4th Week
During the 4th week the Blastocyst fully attaches itself to the uterus wall. It can now be called an embryo. It also develops minute hair like projections to fasten itself to the blood vessels of the mother’s body. The placenta thus begins to form from such projections. Within one or two days the umbilical cord along with other membranes forms that secures the embryo. During this 4th week of pregnancy you will surely going to miss one of two of your periods. This is a positive sign confirming your pregnancy.
