Changes occur during 2nd week of pregnancy

Baby's Development -

This may sound strange, but woman are still not pregnant.  Under the influence of hormones, ovulation occurs and the egg bursts out of its follicle. If it meets a sperm, woman may become pregnant. Fertilization of egg by the sperm will only take place near the end of this week.

Woman's Body -

Woman's uterine lining is developing, which will nourish the baby, and body secretes follicle stimulating hormone (FSH), which stimulates an egg to mature. At the end of this week, woman will be at the midpoint of her menstrual cycle and ovulation will occur (ovary will release an egg into the fallopian tube). At this time, woman is most likely to conceive. If woman has sexual intercourse without protection around the time, she can become pregnant.

What is Pregnancy

Pregnancy is the fertilization and development of one or more offspring, known as an embryo or fetus, in a woman's uterus. Childbirth usually occurs after approximately 40 weeks from the start of the last menstrual period (LMP).

Symptoms of pregnancy include the absence of menstrual periods, morning sickness, breast changes, tiredness, nausea, mood swings, or other symptoms. A pregnancy test measures the human chorionic gonadotropin hormone in the urine or blood.

By the end of 37 weeks, a baby is considered full term and its organs are ready to function on their own.

Uterine Contraction and Retraction

Uterine contraction :-

It is the temporary shortening of the uterus muscles for starting the labour process. In easy way, contraction is essential for starting the labour. It is very difficult or impossible to born baby without contraction in normal delivery.Because in this process, the uterus muscles becomes short and space in uterus becomes less, so pressure is increased in uterine cavity. This pressure push down the baby in lower portion of uterus and force the baby to delivery. It starts naturally but in some conditions or in emergency, contraction is induced manually for saving the baby or woman.


Uterine retraction :-

Retraction is a phenomenon of the uterus in labour in which the muscle fibers are permanently shortened. Unlike any other muscle of the body, the uterine muscles have this property to become shortened once and for all. It is the permanent shortening of the uterine muscle fibers for help in controlling the postpartum haemorrhage. In other way, retraction is very important process for stopping the bleeding. After delivery, bleeding starts by separating the placenta from uterine wall, it is called postpartum haemorrhage. It is dangerous to woman's health if not controlled, so naturally retraction process occur. In this process, the blood vessels are blocked and closed to it's uterine end.
