Overview

In the fourth week of pregnancy, 28 days have elapsed since the beginning of your last period. Fertilization has occurred, symptoms have become persistent, and there’s no longer any ambiguity about the pregnancy itself.

Your baby (still referred to as a blastocyst) has officially begun its foray into physical development. While still microscopic in size, the blastocyst will start forming a tiny face with barely formed eyes and nose within the next week.

At four weeks, your blastocyst is now also officially an embryo and has begun its foray into the embryonic stage. Very soon your babies various body parts and organs will begin their formations while the amniotic sac will rapidly begin to enshroud the embryo to safely and comfortably keep your baby secure during your pregnancy term.

It’s an exciting time for mothers-to-be. The psychological impact involved from discovering the fact that their fertilized egg has now started to take its beginning developments into human form is deeply profound. For many mothers, the pregnancy becomes very “real” at this point. Many women who found themselves still struggling to kick harmful habits like smoking and drinking often find themselves kicking the habits for good overnight after fully realizing how real things have become.

For some women, it takes the sight of their baby on an ultrasound to stun them into transformative action. For others, it might take the news from their doctor that their baby is now on theprecipice of developing a face with the beginnings of a nose and eyes. Many will have reached their own epiphany while in week three of pregnancy after discovering that the sperm and egg union resulted in a chromosomal human blueprint for their future babies.

Week four is an imperative time to crack down on maintaining good health and dietary habits. Folic acid should be taken daily in conjunction with vitamin D. With the blastocyst on the cusp of undergoing rapid physical development, the need for vitamin D becomes immediately important.

If you haven’t already, a visit with your doctor must be scheduled. Your doctor will go through a comprehensive list of questions to help guide you through and achieve a healthy and successfuldelivery. Many issues will be addressed including any mental health problems and corresponding medications along with the presence of sexually transmitted diseases that can severely impact a baby’s health.

Your doctor’s visit is an opportune time to bring up the most pressing questions that you have about your pregnancy. Be prepared by writing a list of your questions and concerns and bring it with you to the appointment along with a pen and paper to take notes that you can review later.

Some important concerns you may want to address with your doctor at this initial appointment are any health issues that you have, prescription medications you consume, or previous pregnancy problems that could potentially impact the health of your baby.

Your Baby’s Health and Status

4 Weeks Pregnant – Baby’s status

The fourth week of pregnancy heralds the official beginning of what’s called the embryonic period. Lasting from the fourth until the tenth week, the blastocyst will begin transforming into a baby with the development of functioning organs.

Still microscopic in size, your baby is a tiny ball of cells embedded comfortably in your uterus and undergoing rapid transformative measures that mark the beginning of a fast-paced six-week developmental chapter that will culminate in incredible results.

Tips, Tricks, and Knowledge

  • By week four you should be including vitamin D in your supplement routine. Along with 400 micrograms daily of folic acid, take vitamin D. Liquid vitamin D drops are best as they are the most bioavailable form for your body. Just a tiny drop or two once per day will take care of your vitamin D needs for you and your growing baby.
  • You may require higher dosage folic acid. At your initial visit with your doctor, have a conversation about folic acid supplementation and see what he or she recommends. Simple blood work can yield valuable information about the folic acid levels your body requires for optimal health.

  • Even if you eat many foods high in folate, continue supplementing with folic acid
