DOC I AM PREGNANT
Pregnancy is the carrying of a fetus or embryo in the womb of a woman.
The term embryo is used to describe the developing offspring during the first 8 weeks following conception while the term fetus is used from about 2 months of development until birth.
Human pregnancy is divided into three trimester periods:
1.The first trimester carries the highest risk of miscarriage (natural death of embryo or fetus).
2.The second trimester, the development of the fetus can be more easily monitored and diagnosed.
3.The third trimester often approximates the ability of the fetus to survive outside of the uterus.
Fertilization
The process leading to pregnancy occurs earlier usually in the fallopian tube when the female egg is penetrated by the male spermatozoon following the act of sexual intercourse.
This process is referred to as fertilization or conception.
The fertilized egg then travel down the fallopian and implants itself into the inner lining of the womb or uterus.
Once implanted in the uterus the embryo will grow to become a fetus at 2 months before coming out of a normal pregnant mother's womb at 38 weeks from conception to become a newborn baby.
After implantation into the lining of the womb, the embryo secretes a hormone named human chorionic gonadotropin which in turn stimulates the corpus luteum in the woman's ovary to produce progesterone.
The progesterone act to maintain the lining of the uterus so that the embryo will continue to be nourished by the glands in the lining of the uterus.
The capillaries will be stimulated to grow from the wall of the uterus to form the placenta which allow the embryo to receive vital nutrients from the woman's blood supply.The umbilical cord is the connecting cord from the embryo or fetus to the placenta and allow nutrient uptake, waste elimination, and gas exchange via the mother's blood supply.
The expected date of delivery is 40 weeks counting from the first day of the last menstrual period and birth usually occurs between 38 and 42 weeks.Even though pregnancy begins at conception, it is more convenient to date from the first day of a woman's last menstrual period.
Diagnosis of pregnancy:
The beginning of pregnancy may be detected by a pregnant woman without medical testing through a number of symptoms of pregnancy:
1. nausea and vomiting,
2. excessive tiredness and fatigue,
3. cravings for certain foods
4. frequent urination particularly during the night.
Signs of pregnancy include:
1.the presence of human chorionic gonadotropin (hCG) in the blood and urine can be detected as early as 12 days after implantation
2.missed menstrual period,
3.implantation bleeding during the third or fourth week after last menstrual period,
4.increased basal body temperature sustained for over 2 weeks after ovulation,
5.Chadwick's sign (darkening of the cervix, vagina, and vulva),
6.Goodell's sign (softening of the vaginal portion of the cervix),
7.Hegar's sign (softening of the uterus isthmus),
8.pigmentation of linea alba – darkening of the skin in a midline of the abdomen, caused by hyperpigmentation resulting from hormonal changes, usually appearing around the 22nd week of pregnancy
9.Breast tenderness and darkening of the nipples is common
10.an early obstetric ultrasonography can determine the age of the pregnancy fairly accurately based on the last menstrual period.
