Your pregnancy at Week 4

Highlights: #

Your Baby at Week 4 #

Two sets of cells
Your itty bitty embryo has two layers of cells called the epiblast and the hypoblast. Soon they’ll develop into all of your baby’s body parts and systems.

Seeing double
You normally don't have your first ultrasound until at least week 6, but you might be able to spot the gestational sac as early as halfway through week 4 — and if you're having twins, you'll likely see two of them!

Baby's yolk sac
Before the placenta forms, you develop a yolk sac, which can be visible next week. This sac produces blood and helps to nourish your young embryo.

Your Body at Week 4 #

No symptoms yet?
At 4 weeks pregnant, your body is gearing up for pregnancy, but some women may not feel any symptoms yet. Early pregnancy symptoms like mood swings, bloating, and cramping can occur, but not everyone experiences them.

The egg implants
Implantation occurs this week as the blastocyst attaches itself to the uterine lining. Some women may experience implantation bleeding, which is usually very scant and light in color.

Pregnancy hormones will soon make an appearance
Within six to 12 days after fertilization, the egg starts to release hCG, the pregnancy hormone that will turn a pregnancy test positive.

Pregnancy Symptoms in Week 4 #

Implantation bleeding
Some women may experience spotting around the time they would have had their period, which could be a sign of implantation.

PMS-like symptoms
Pregnancy hormones can cause various symptoms similar to premenstrual syndrome (PMS), including moodiness and bloating.

Things to Take Care in Week 4 #

Don't forget vitamin D
Ensure you're getting enough vitamin D from sunlight, fortified milk, or supplements.

Find your due date
Calculate your estimated due date, but keep in mind that most babies are born between 38 and 42 weeks.

Healthy fats are good fats
Consume essential fats like omega-3 fatty acids, especially DHA, which is crucial for your baby's brain and eye development.

Avoid secondhand smoke
Exposure to secondhand smoke may increase the risk of complications during pregnancy.

Try a new comfort food
If your usual comfort food is making you sick, try switching to another comforting option.

Make a prenatal appointment
Schedule your first prenatal appointment with your doctor or midwife as soon as you have a positive pregnancy test.

Stave off food poisoning
Avoid undercooked proteins and raw dairy or juices to prevent foodborne illnesses during pregnancy.
