A full guide on the Stages of Pregnancy

Pregnancy, also called gestation, is a period after the fertilization of the egg when the fetus grows in the mother's womb till the baby is delivered. It usually lasts about 9 months or 40 weeks from the last day of your menstrual flow. 

This guide will help you understand everything you need to know about the stages of pregnancy. 

Stages of Pregnancy

The stages of pregnancy is divided into three called trimesters. As such, the first trimester lasts from week one to week twelve, the second trimester from week thirteen to week twenty-six, lastly the third trimester lasts from week twenty-seven to the end of pregnancy birth.

Each part of the trimester is marked by its peculiarities, as you will soon discover for both mother and baby. 

When does pregnancy start?

When does pregnancy start?

Before we go further, we want to address a question that has stirred a lot of debate in recent times especially between the pro-life and pro-choicers side of the pregnancy termination. 

When does pregnancy start? The truth is, there are a lot of variables that make answering this question tricky at best. For you to land a verdict that is somewhat accurate or satisfactory you will need to consider the events that gave rise to pregnancy in the first place conception and implantation.

Conception

After intercourse, 300 million sperm are released in the medium called semen. This is the story of an epic battle for one of the sperms to fertilize the egg in the face of incredible odds. For this fertilization to turn a success, the egg has to be first released in the process called "ovulation" aided by the interplay of the female hormones.

This number is cut short when a good number of sperm are flowing out of the vagina and some other millions die due to the acidity of the vagina.

Notwithstanding, a lot still survive, courtesy of the alkalinity of the semen. Those who survive swim towards the cervix. The cervix is a cylindrical tissue lower part of the tissue that connects the uterus to the vagina. The cervix is normally tightly closed to keep the pregnancy in place and only dilates when it is time to deliver. It also slightly opens when the woman ovulates letting her drain menstrual flow.

The sperms pass through the lumen of the cervix to get to their distinction to the egg in the fallopian tubes. Some millions are caught up in the cervical mucus and subsequently die off, others fall behind and in time will be the backup, while some keep the foot on the gas to get the destination.

The remainder swims towards the tubes, one-half swim towards the tube containing unfertilized egg while the other half swim towards the other tube containing fertilized egg. 

In the fallopian tubes, the motion of sperm is facilitated by the female genital tract that also releases certain chemical factors that cause changes in the sperm and makes them swim faster. 

The sperms reach their destination, the egg. The sperm later fuses with the egg in a process called conception or fertilization. This is when the life of a little one has started. It should also be remembered that it is now that the sex of the baby is determined.

Implantation

Implantation is the aftermath of the events of fertilization. The fertilized egg stays in the fallopian tube and starts active exponential division. After 6-7 days after fertilization, the zygote, now embryo, moves to and implants on the lining of the uterus. The motion of the fertilized egg is aided by the motion of the cilia that directs it to the uterus. In a related development, the uterus gets thicker and the cervix is sealed off by a mucus plug.

This implantation is accompanied by spotty bleeding called implantation bleeding after 1 or 2 days  And sometimes cramps that most women mistake for the usual menstrual cramps. 

There is a lot that can happen between point A fertilization and point B implantation. The egg can be implanted in the wrong site ectopic pregnancy and cause serious complications in the mother if not medically addressed in the proper manner and time. As a rule of the thumb, any pregnancy that implants in the wrong site must be removed surgically. Hence, an egg may be fertilized by not implanting properly, and this sums up the argument. Fertilization is as important as implantation.
