3 week pregnant

A woman’s third week of pregnancy can come and go with little fanfare. Often there’s not much in the way of new symptoms that deviate from symptoms that may have been experienced in weeks one and two and emotional and physical effects can remain more or less at the same level. However, it’s imperative to note that pregnancy is different for every woman. While many women may truly feel the same in week three as they did in week two, there are legions of women who very suddenly begin to experience new physical and emotional symptoms that are classic hallmarks of pregnancy.

Regardless if you are experiencing much of the same overall symptoms as week two or if you are instead developing new symptomatology, it is at this time that critically important changes are occurring within the confines of your body in the form of myriad advances for baby taking place at a rapid-fire pace.

By the third week of pregnancy, the sperm and egg will have united, transformed into a blastocyst that will have journeyed from the fallopian tube to the uterus, and ultimately embedding itself within the womb’s lining.

A comprehensive incorporation of genetic material of will have also taken place, and the sex of your baby will have been established by this point. With 23 chromosomes received from you and an additional 23 chromosomes received from your partner, 46 chromosomes ultimately determine the baby’s physical traits such his or her eye color, hair color, personality traits and far more.

At this point, the blastocyst will continue to undergo swift changes and rapid development to ultimately culminate in a “real” baby in about the span of 9 months.

Week three is when your pregnancy truly begins. It is at this time in the pregnancy time spectrum that it becomes “official,” with all benchmarks met including the successful union of sperm and egg, the subsequent transformation of the union and incorporation of genetic material, and the rapid journey from the ovary to the Fallopian tube and finally the uterus where fertilization has commenced, and cell division begins to occur expeditiously.

For those women who visit a sonographer during the third week of pregnancy, many will be able to view the exciting and fascinating beginnings through an ultrasound viewing.

Your Baby’s Health and Status

3 Weeks Pregnant – Baby’s status

By week three, your baby has undergone the implantation process where its fertilized egg form has successfully gained entry to your uterus and housed itself within the lush, dense, and blood-rich lining of the uterus. As funny as the term may sound, in medical terms your baby is at this point referred to as a blastocyst.

Full of countless multiplying cells, the blastocyst suddenly becomes accompanied by amniotic fluid which serves to cushion your baby in the coming months. A part of the blastocyst will form into the placenta and will have begun the production of hCG pregnancy hormones that increase the levels of hormones like progesterone and estrogen.

The increase in the progesterone and estrogen hormones serve to halt uterine lining shedding and render it secure and intact to house the blastocyst in addition to also communicating to your body that your ovaries can halt egg releasing processes.

Tips, Tricks, and Knowledge

3 Weeks Pregnant

  • Making lifestyle changes doesn’t have to be difficult. Make substitutions whenever possible. Be creative and have an open mind. Pregnancy doesn’t mean you have to live a Spartan existence. If you previously enjoyed a nightly glass of wine, try a cranberry juice, and seltzer mixer served in a real wine glass to replicate the experience as best you can. It’s a delicious substitution, and the cranberry juice has the added benefit of assisting in urinary health function
  • If you are experiencing exhaustion, don’t be concerned. It’s perfectlynormal and results from the increase in progesterone and the internal “work” taking place inside your body as your baby starts its beginnings
  • Bleeding or spotting is normal in small amounts. However, if you experience pain when spotting, make an appointment with your doctor as soon as possible because this may be an indication of an ectopic pregnancy

Week 3 To-do List and Reminders

3 Weeks Pregnant

  • Start making plans for a new life with a new baby; visualize the needs of your infant and take a keen look at your home, car, and overall living situation. Do you have a sporty two-door coupe? You may want to start saving up to trade your vehicle in for a roomier car that can easily accommodate a car seat and provide accessibility for mother and child
  • Consider your work situation. Investigate pregnancy leave policies and timeframes
  • Analyze your work hours; after a leave of absence from work, will you be requiringdaycare?
  • Start budgeting for the new addition to your family – consider expenses such as diapers, formula or breast pump supplies, baby furniture, and more

Keywords

Implantation: Occurs when the fertilized egg attaches itself to the newly transformed thick, dense, and lush uterine lining, typically occurring roughly 6-7 days post conception
Amniotic fluid: A densely rich source of critically important stem cells, Amniotic fluid is a clear yellow-tinged liquid that basically encases your baby within the Amniotic sac. Appears around the three-week mark and begins to surround the fertilized egg as a means to protect and cushion your baby in the coming months while also providing your baby with crucial nourishment.

Ectopic pregnancy: 1 out of every 50 pregnancies are Ectopic in nature. Occurs when the fertilized egg travels to a destination other than the uterine lining and attaches itself in a different location such as the fallopian tube. Fallopian tubes cannot accommodate a developing embryo; as such immediate medical attention is required to address this critical situation

Cool Things to Know

  • While the sex of your baby has been established by week 3 (along with many other factors such as hair and eye color), you won’t be made aware of your baby’s sex for atleast a couple more months
  • A fertilized egg contains 23 chromosomes from you and 23 chromosomes from your partner to total 46 chromosomes that ultimately create the blueprint of your baby’s physical and emotional traits and attributes. As a woman, you will be the provider of the X chromosome, but your partner can provide either an X or a Y. If he provides an X, then you will have XX, which means you will have a girl. If he provides a Y, you will have XY, which means you will have a boy.
