Baby's Development at 7 Weeks
The embryo's brain is expanding so rapidly that the head makes up nearly half of its total length. Hands and feet are forming from what were paddle-shaped buds just last week, and you can see the beginnings of fingers. The face is becoming more defined — the nostrils are open, the retinas of the eyes are pigmenting, and the tongue is forming. The kidneys are in place and beginning to produce urine. The umbilical cord is now fully functional, delivering nutrients and oxygen from the placenta.
Your Body at 7 Weeks Pregnant
Week seven is often peak misery for morning sickness — hang in there, it usually starts to ease after week 10. Food aversions can make eating challenging; follow what sounds tolerable even if it's not nutritionally perfect. Bloating and constipation are common thanks to progesterone slowing digestion. Heightened emotions and mood swings are normal as hormones fluctuate. Some people also experience dizziness or lightheadedness.
Tips for Week 7
- Eat whatever you can keep down — this is not the time to stress about a perfect diet.
- Stay hydrated; dehydration worsens nausea significantly.
- Consider telling your employer soon if nausea or fatigue is affecting your work — you're protected from early pregnancy discrimination.
- Prenatal yoga classes are a great way to stay active and connect with other expecting parents.

Frequently Asked Questions
Why is morning sickness worst around week 7?
hCG (human chorionic gonadotropin) levels peak between weeks 8 and 11, and hCG is the hormone most strongly linked to nausea and vomiting. Week 7 is right in the run-up to that peak, which is why so many people feel at their worst during this window.
Is brown discharge normal at 7 weeks?
Light brown spotting or discharge in early pregnancy is usually old blood making its way out and is often harmless. It can happen after sex, a pelvic exam, or for no apparent reason. Bright red bleeding with cramps is a reason to call your provider promptly, but brown spotting alone in the first trimester is very common.
