Pregnancy Week 7: What to Expect
Baby's development, your body's changes, common symptoms, what to eat, and what to do this week.
Baby's development at week 7
Baby's brain is growing rapidly — new neurons form at about 100 per minute this week. The face takes more shape: nostrils appear, dark eye spots gain a lens, ear canals indent further into the head. Tiny tooth buds form under the gums. Arm and leg buds lengthen and start to differentiate — paddles where hands and feet will be. The umbilical cord is fully working, carrying oxygen and nutrients from you to baby and removing waste. Baby's kidneys and intestines begin to form.
What's happening in your body
Pregnancy hormones (hCG, progesterone, estrogen) are at or near peak levels. Your blood volume continues to climb, and your heart works harder — heart rate increases by about 10-15 beats per minute compared to before pregnancy. The mucus plug is fully sealed. Many people find their gums feel tender or bleed slightly when brushing because higher blood volume affects gum tissue too. Excess saliva (called ptyalism) hits some people hard during weeks 6-10.
Common symptoms at week 7
Nausea often peaks this week or next. Excessive saliva production for some — having to spit constantly is a real, normal symptom. Vivid dreams from hormone shifts. Bloating and constipation. Heightened sense of smell. Possible mild dizziness if you stand up too fast. Breast tenderness, sometimes with darker areolas. Mild fatigue or full-on exhaustion, with the body needing 9-10 hours of sleep when usually 7-8 was enough.
When to call your provider
Severe nausea that prevents any food or liquid intake for 24+ hours, signs of dehydration (dark urine, dizziness, dry mouth), severe abdominal pain, or any heavy bleeding — call your provider. Mild spotting alone is usually fine, but always worth mentioning.
How to feel better this week
Brush teeth gently with a soft brush; floss carefully but consistently — pregnancy gingivitis is common and treatable. Carry a small bottle of water everywhere. Try acupressure wristbands (Sea-Bands) for nausea — they help some people and have no side effects. Ginger candies, lemon drops, or cold green apple slices work for others. Avoid lying down right after meals to limit reflux. Sleep on your side if you can. Take naps without guilt; the fatigue is not laziness.
Nutrition focus for week 7
Protein every few hours stays the most reliable nausea-bluntener. Smoothies with banana, yogurt, peanut butter, and spinach (you can hide a lot in a smoothie) get many nutrients into someone who cannot stomach normal meals. Vitamin B6 supplementation (under provider guidance) helps about half of people with nausea. Avoid an empty stomach — even at 3 a.m. when you wake up needing to pee, eat a couple of crackers before lying back down.
For your partner
If your partner is dealing with extreme nausea, do not eat foods near them that trigger it. Take over driving (motion makes nausea worse), grocery shopping, and cooking. Recognize that they may not be able to think clearly through the fatigue and brain fog — be patient with forgotten conversations.
This week's to-do
Stock up on nausea-friendly snacks. Brush teeth and floss daily. Call provider if nausea is preventing any food intake for 24+ hours.
Is this normal?
Severe nausea (hyperemesis) affects about 1-3% of pregnancies and is medically treatable. It is not "just morning sickness" — there are prescription options. Do not white-knuckle it if you cannot keep anything down.
