Last Menstrual Cycle
The menstrual cycle can be divided into several different phases. The average length of each phase is shown in the photograph, The first three are related to changes in the lining of the uterus whereas the final three are related to processes occurring in the ovary. -
Period: to
Pregnancy in a woman
-
Ovulation
The release of LH matures the egg and weakens the wall of the follicle in the ovary, causing the fully developed follicle to release its secondary oocyte.The secondary oocyte promptly matures into an ootid and then becomes a mature ovum. The most fertile period covers the time from some 5 days before until 1 to 2 days after ovulation -
Fertilization
If one sperm does make its way into the Fallopian tube and burrow into the egg, it fertilizes the egg. The egg changes so that no other sperm can get in.
At the instant of fertilization, your baby's genes and sex are set. If the sperm has a Y chromosome, your baby will be a boy. If it has an X chromosome, the baby will be a girl. -
Implantation
If conception occurred, implantation typically happens seven to ten days after ovulation, but it can happen a few days earlier or later as well.
•light spotting happens for just a brief period of time around seven to ten days past ovulation. -
Embryonic and Fetal Development Begins
The fifth week of pregnancy, or the third week after conception, marks the beginning of the embryonic period. This is when the baby's brain, spinal cord, heart and other organs begin to form. -
Baby's Head Develops
five weeks after conception, your baby's brain and face are rapidly developing. Tiny nostrils become visible, and the eye lenses begin to form. -
Limbs Developing
six weeks after conception, your baby's arms and legs are growing longer, and fingers have begun to form. -
Week 7
In the ninth week of pregnancy, or seven weeks after conception, your baby's arms grow, develop bones and bend at the elbows. Toes form, and your baby's eyelids and ears continue developing. -
Baby's developing rapid
Paddle-like, or webbed, hands and feet will now separate into fingers and toes, bones will begin to harden and his kidneys are now producing urine. -
Breathing Underwater
At weeks 10 and 11, the fetus will start to inhale and exhale small amounts of amniotic fluid, which helps your baby's lungs to grow and develop. -
Second Trimester
15 weeks pregnant. (fetal age 13 weeks)
•Baby is now over 4 inches (10cm) long
•and weighs about 2.5 ounces (75 grams).
•He or she can move its arms and make a fist.
•Fingernails and toenails are present.
•Baby's skin is still very thin.
* Muscles are developing and bones are getting stronger. -
16th Week
More developed facial muscles may lead to various expressions, such as squinting and frowning. Your baby nows weighs more than their afterbirth. The baby can grasp with his hands, kick, or even somersault.
•Baby hears external voices, sleeps and dreams
The heart is pumping 25 quarts of blood a day.
The fetus has an adult's taste buds and may be able to savor the mother's meals. -
Ultrasound time (5th month)
Your baby may hear your heart beating, your stomach rumbling or blood moving through the umbilical cord. He or she may even be startled by loud noises.
The internal organs are maturing. Fat is now being stored beneath your baby's skin. Your baby's gall bladder will become functional, producing bile that is necessary for digestion. -
Sixth Month
The fetus measures about 36 cm from head to toe at this time.
His fingers, toenails, eyelashes and eyebrows are present and will grow until he is born. -
The Last Months of Fetal Development
Eyeteeth are present. The baby opens and closes his eyes. The baby is using four of the five senses (vision, hearing, taste, and touch.) He knows the difference between waking and sleeping, and can relate to the moods of the mother. The baby's skin begins to thicken, and a layer of fat is produced and stored beneath the skin. Antibodies are built up, and the baby's heart begins to pump 300 gallons of blood per day. Approximately one week before the birth the baby stops growing. -
Stages of Labour
Labor has three main stages,
The first stage is when the cervix dilates. It has to reach at least 10 cm for the baby to get out. The second stage is when you give birth, and the final stage is when the placenta leaves the body.
