How far along are you at 4 weeks?
Your journey of growing an egg into a tiny little human whom you will pop out in 9 months from now, has officially begun. The first few weeks are the most crucial. Though you may not notice any early pregnancy signs during this week, your body has started some amazing transformations.
Your body is busily transforming an egg into an embryo.
During week 1, your body is preparing a new and hospitable uterine lining to nest the fertilized egg. Meanwhile, a couple of dozen of eggs test their luck to develop, ovulate and rupture the follicles (tiny sacs of fluid) because only the fittest will survive to week 2. More than one means twins and so on.
The egg, now known as an ovum, travels down through the fallopian tube to meet with the sperms which were ejaculated into your vagina. Every sperm starts to race to get to the egg first. Their motto is to get attached to the egg as they might be waiting in your body for as long as 6 days.
Now, this procedure is a marvel in itself. Once the ovary releases the egg and it descends the fallopian tube, it will pass through your body via the menstruation flow if not fertilized within the next 12-24 hours time crunch. But, the sticky structure on one end of the sperm helps it to attach itself to the egg, and then it penetrates through the lining of the shell making the egg fertilized.
People often think that the date of intercourse is the date of conception. Whereas, it can take up to 3 days for the sperm to meet the egg and then fertilize it. It is difficult to calculate exactly when the egg was fertilized. Therefore, the doctors usually calculate your probable due date from the first day of your last period.
Your fertilized egg is now known as an embryo. The embryo is now on a journey through your fallopian tube` to its permanent home for the next nine months, the Uterus. It is growing into many folds as it travels down the fallopian tube but still is as small as a grain of salt. When the embryo will enter the uterus, it will be around 200 cells bigger than the original size.
During this week, the embryo is jumping around in your uterus to find a comfy spot to settle. As soon as the embryo finds the perfect spot, it implants the lining.
An ectopic give link to ectopic pregnancy may occur if the egg implants somewhere in the fallopian tube. Ectopic pregnancy means “out of place” pregnancy. Or when the fertilized egg is implanted anywhere outside the uterus. Although it is a rare occurrence it may cause life-threatening bleeding in the first trimester.
As the embryo finds its comfy spot and implants the lining. You may experience some bleeding also known as implantation bleeding. Link to early symptoms of pregnancy. The cells of the baby are on a growth spurt. They are multiplying and getting stronger with every passing minute.
The cells are working really hard to perfectly inhabit the lining of the uterus. The cells are also working towards establishing contact with the blood circulation of your body to attain more blood supply for growing the baby.
A spiking change in the hormonal level can now be noticed as your placenta is producing the pregnancy hormones which are estrogen, progesterone, and human chorionic gonadotropin (hCG). Even at this point, an ultrasound cannot see your baby.
Your baby is thriving. However, you won’t be able to catch the glance. Even though the baby is growing at a speedy rate, it’s still smaller than a sesame seed and hence cannot be captured in the ultrasound. As the cells keep multiplying, a group of the most essential group of cells has started to form.
- The Ectoderm. It will develop into the baby’s skin, brain, nervous system, and other external tissues as it is the most exterior germ layer.
- The Endoderm: It will become the lining of the gut and other internal organs like the liver, thyroid, pancreas as it is the most internal germ layer.
- The Mesoderm: As the middle germ layer, it forms the baby’s skeleton system, blood circulatory system, muscles, urogenital organs, and connective tissues.
