4th Week Pregnancy Highlights

You Have a Date!

Based on the first day of your last menstrual period, your doctor will now give you an estimated due date. Now, remember, we were the first ones to tell you to keep those dates handy!

Baby Bulletin

Your baby is now an embryo. Very soon, the baby’s nervous system, connective tissues, and organs will all begin to develop.

What You Need To Do

Consider doing carrier screening, like LifeCell’s GenePass Carrier screening panel, a simple blood or saliva test to check if the baby is at risk for any genetic disorder.

Pregnancy Milestone

You’re now into week 4. At the end of this week, you’ll complete a month of pregnancy!

How Big is Your Baby?

Here we are at last! The tiny embryo has formed two distinct layers of cells, and these cells are building blocks of your baby’s organs and body parts. There is now a placenta around the embryo which will continue to thicken until the fourth trimester. The placenta transports the different nutrients and a sufficient amount of oxygen to your baby.

4th Week Pregnancy Symptoms

When women get a positive pregnancy indication, it is often in their 4 or more weeks of pregnancy. Therefore, you are most likely to miss your period, which is the major symptom. You may easily get a red streak in your pregnancy test kit by now. But make sure to take the test at the end of the week for better accuracy.
