Little Genius with Paddle‑like Hands
Your embryo is already about 1 centimeter long, yet grand processes are occurring in this tiny body.
What’s happening this week:
- Limbs: Hands and feet are lengthening, although the fingers are not yet separated.
- Brain: Brain development is in full swing, with the main regions forming.
- Face: Eyelids, the tip of the nose, and the mouth continue to develop.
- Internal organs: The kidneys have taken their final position and will soon start producing urine. The liver, pancreas, and appendix are also developing.
Even though they are still so tiny, your baby already has its own circulatory system, and the heart is efficiently pumping blood.

When Everything Nauseates: Peak Nausea
The seventh week often becomes the most challenging in terms of morning sickness. hCG levels reach their peak, which can intensify nausea, fatigue, and emotional instability.
New and familiar sensations:
- Food aversions and cravings: A favorite dish may become repulsive, and conversely, you might intensely crave something unusual, like salty pickles with honey.
- Excessive salivation: Some women are bothered by this strange but common symptom.
- Acne: Hormonal changes can trigger skin breakouts, even if you’ve never had them before.
- The uterus is growing: It has already doubled in size, although it’s still not noticeable externally.
Remember, you are not alone. There are ways to ease this condition. Read about them on our blog: "10 Ways to Survive Nausea".
Overview
Week 7: Hands, Feet, and Rapid Brain Growth
In the seventh week, your little one, the size of a blueberry, is undergoing an incredible stage of development. Although you may not feel it yet, they are moving actively and changing every day.
The main events this week are the formation of tiny hands and feet, which currently resemble small paddles, and an extraordinarily rapid brain development. About 100 new brain cells are formed every minute!
This week may be a peak of morning nausea and fatigue for you. Remember, this is a sign that pregnancy hormones are actively working to support your baby's development.
This is the time when the foundations of intellect and future movements of your baby are laid. Every day matters greatly.
All these changes are part of the amazing process described in detail in our article "Fetal Development by Week".
Tips for mom
Survival Strategy: Eat, Drink, Rest
Right now your main task is to find a way to get nutrients and fluids despite the nausea.
What may help:
- Eat what you can. If all you can manage are crackers and bananas—let it be. It’s better than nothing.
- Vitamin B6 and ginger. Talk to your doctor about the possibility of taking vitamin B6 or using ginger (as tea or capsules) to ease nausea.
- Buy a comfortable bra. Your breasts continue to grow and become more sensitive. Comfortable, wire‑free underwear can be a real lifesaver.
- Consider when to share the news. Many couples wait until the end of the first trimester. Discuss what feels most comfortable for you.
Even if you have no appetite, it’s important to understand what the baby needs. Read the article about essential vitamins and nutrients to know where to focus.

Master of Finding “Safe” Food
This week your culinary and logistical skills may be more useful than ever.
Your contribution to the family’s peace:
- Be the “food hunter.” If she suddenly craves watermelon at 10 p.m., try to find it. Satisfying her whims isn’t pampering; it’s helping the body get what it demands.
- Offer to handle the shopping. The supermarket, with its myriad of smells, can be a real nightmare for her.
- Encourage her to rest without guilt. Take over household chores so she can nap.
- Plan finances. This is a good time to start discussing upcoming expenses. Our article on financial preparation can be a starting point.
