Introduction

The definition of Pregnancy could be simply put as the series of events which usually take place throughout the duration of pregnancy of females. Moreover, these events usually end up with the birth of the child after duration of 40 weeks or 280 days. Moreover, before duration the chain goes back from fetal growth, embryonic growth, implantation to fertilization. Pregnancy is a time period in which the changes occur in all of the woman's body. First of all, it is a hormonal period, when a sharp increase in progesterone, estrogen and other hormones completely changes the functioning of the body. These changes are necessary to ensure the proper development of the fetus, as well as to prepare women for childbirth, postpartum and breastfeeding. They are completely safe for the expectant mother and the baby, but they can cause severe, bothersome symptoms. The most common are headaches, nausea, vomiting, fatigue, emotional lability, shortness of breath, leg heaviness and swelling distal parts of the body, and finally, back pain. In this article I would like to take a closer look to these processes and explain which ones are responsible for the most frequently mentioned by the future we ailments.

As per the human biology, pregnancy refers to the fertilization from a female's egg that consists of 23 chromosomes in combination with a male sperm that consists of the 23 chromosomes of the other side (Kane, 2009, p.228). In total, these reach up to 46 chromosomes, that are required for the construction of a human body. By the combination of the highlighted cells retrieved from the biologically identified father, the creation of an embryo takes place that is then placed inside the uterus for growth for gestation which consists of 9 months in total. Moreover, this process continues till the time of delivery arrives, that might take place in the form of childbirth by the natural form or through the usage of caesarean section which is counted among the surgical techniques (Jenkins, 2011, p.286).

Background

During pregnancy, progesterone increases many times, the peak dose is 30mg, and after fertilization increased to 75 mg and 40 weeks jumps up to 300mg. This does not happen without a reason, because the hormone fulfills many functions in the preparation of the woman's body for the development of the fetus and its activity covers virtually all body systems. Progesterone is a female sex hormone produced by the ovaries in small quantities, which acts in the female body by appropriate receptors located such in the uterus and mammary gland. Every month, along with estrogen on the endometrium prepares to receive the embryo, and if fertilization does not occur to causes exfoliation of endometrial cancer and the expulsion of the blood (i.e. menstruation).

After fertilization progesterone stimulates the mucous membrane of the uterus and fallopian tubes to release nutrients and is a substrate for the production of glyco-and mineral corticoid fetus. It is a hormone necessary to maintain pregnancy, as one of its main tasks is ...
