Congratulations! You’re in for an exciting ride, my dear. Pregnancy is a magical experience that’s both joyous and challenging at the same time. By now, you’ve probably heard about the different stages of pregnancy – from conception to delivery – but do you know what happens during the fetal stage? Well, buckle up because we’re about to take a deep dive into the world of fetus development.
Let’s start at the beginning: What is fetal stage?
The fetal stage is basically when your baby starts looking like… well… an actual human baby. This period starts from 9 weeks after fertilization and continues until birth (which could be between 37-42 weeks in total). During this phase, your little munchkin grows rapidly and undergoes some mind-blowing changes that prepare it for life outside your womb.
Week-by-week guide: What happens during each week?
Wait, what? I thought we were talking about fetal development here! Don’t worry; every story has its backstory. Technically speaking, fertilization happens around week two of pregnancy (although most women only become aware of their prego state after they’ve missed their period by two weeks). So yes – technically – these first two weeks count towards gestational age as per medical terminology but nothing significant occurs during this duration except zygote division leading up to blastocyst formation which allows implantation into the uterine lining thus marking official pregnancy initiation
Weeks 3-4: From Zygote To Baby Shapeless Bunch Of Cells
This is where things start getting interesting! Your embryo measures no more than one millimeter long as cells begin dividing rapidly into three layers – endoderm/mesoderm/ectoderms responsible respectively for functional system formation/organs/bones and muscles/skin/fingernails-toes-nervous system.
Weeks 5-6: Your Little One Gets A Heart And Brain
At this point, your baby is about the size of a lentil! The most notable development during week five and six is that lots more organs start forming such as liver, kidneys, stomach etc., while limbs begin appearing too (albeit still resembling flippers). On the other side of things, fingers and toes separate from one another indicating skin differentiation which means fingernail/toenail growth can now commence.
Oh, but wait… there’s more! Also during this phase the heart starts pumping blood throughout your fetus’ body – albeit not quite fully formed yet with proper pumping action.
Yes you heard that right -the nervous system also begins developing firing nerve cells to enhance control over bodily functions producing rudimentary plexuses to connect vital connector nerves within vital systems that will facilitate organ regulation
Just how big is my precious little one?
Although measurements are taken at different times depending on choice by medical practitioners for checking fetal development; here’s what you could roughly expect in terms of growth across stages:
- End of First Trimester (12 weeks) = About Three Inches
- Midway through Second Trimester (20 Weeks) = Roughly 10 inches
- Third Trimester Length (‘It really depends’) between average values ranging from 19 in. to approximately 21 in.
But hey don’t take it too seriously they come out all shapes and sizes after all wink
From bump-tastic to moving around!
Believe it or not but hands down one thing every mother waits anxiously for is their day(s) long-awaited first Fetal Movement &after patient waiting hours upon blissful hours finally tiny feet palms fingers poking away gradually transition into legs muscles developing granting that mobility.
On an amusing side, you can perhaps predict the continuation of the little athlete by closely observing his/her show-prey instincts as antics such as constant kicking, rolling around womb liners and reacting to fuss or possibly external noise are strongly associated with a possibility of having your future offspring be active on reaching maturity (Good luck!)
