7 Weeks Pregnant

Your baby this week

Your baby is about the size of a blueberry (approximately 10 mm or about half an inch) and the brain is developing at an astonishing rate — generating roughly 100 new brain cells every minute. Facial features are becoming more defined: the mouth, tiny nostrils, ear indentations, and eye lenses are all forming, giving the embryo a more recognizable (if still alien-looking) face. The arm buds now have paddle-like hands, and leg buds are beginning to show the early formation of feet. The liver has taken over red blood cell production from the yolk sac, and the appendix and pancreas are developing. A thin layer of translucent skin is beginning to cover the body, and both kidneys are now in place and will soon begin producing urine.

How you may feel

Frequent urination is now a regular companion — your growing uterus (now about the size of a lemon) is putting pressure on your bladder, and increased blood volume means your kidneys are filtering more fluid. Mood swings may feel more pronounced as progesterone and estrogen levels continue their dramatic rise; you might cry at commercials or snap at minor annoyances. Morning sickness typically continues or worsens, and food aversions may expand — many women develop strong dislikes for coffee, meat, or eggs. You may notice excess saliva (called ptyalism), which is an unusual but normal symptom in early pregnancy. Skin changes such as acne or oiliness can appear as hormones affect your skin's oil production.

Common symptoms

• Morning sickness continues or worsens — this is normal for most women.
• Food aversions and cravings may develop suddenly and strongly.
• Increased saliva production (ptyalism) can accompany nausea.
• Mild cramping is common as your uterus begins to expand.

This week's tips

Schedule your first prenatal appointment if you haven't already — most providers see patients between weeks 8-12 for the initial visit, which will include blood work, urine tests, medical history review, and possibly an early ultrasound. Start a list of questions for your doctor: topics might include genetic testing options, exercise guidelines, medication safety, and what to expect at future appointments. Stay active with low-impact exercise like walking, swimming, or prenatal yoga — aim for 150 minutes per week as recommended by ACOG. Eat iron-rich foods (lean red meat, spinach, lentils, fortified cereals) to support your rapidly increasing blood volume. Practice good oral hygiene, as pregnancy hormones can increase the risk of gum disease (pregnancy gingivitis).

Eating well

• Eat whatever you can tolerate — nutrition can be optimized once nausea subsides.
• Peppermint tea or peppermint candies may help settle your stomach.
• Include fiber-rich foods like whole wheat bread and pears to prevent constipation.

Nutrition focus

• Continue 400–800 mcg folic acid — the neural tube is closing this week.
• Iodine (220 mcg/day) supports your baby's thyroid development — check your prenatal.

Everyday wellbeing

• Gentle stretching and prenatal yoga can ease tension and reduce nausea.
• Wear loose, comfortable clothing — your waistline may start feeling tight.
• Stay well-hydrated; aim for 10 cups of fluid per day.

For your partner

If possible, plan to attend the first prenatal visit with her — this appointment sets the tone for the entire pregnancy and is a significant emotional milestone. Hearing the heartbeat or seeing the embryo on ultrasound for the first time can make the pregnancy feel "real" in a way nothing else does. Start familiarizing yourself with what she can and cannot eat, so you can be a helpful partner when making food decisions. Be patient with her mood swings — a simple "I understand, and I'm here for you" goes further than trying to fix how she feels. Consider downloading a pregnancy tracking app so you can follow along with your baby's development week by week.

Signs to mention to your provider

• Passing tissue or clots along with cramping needs immediate evaluation.
• Fever above 100.4°F (38°C) with chills could signal infection.
• Persistent pain in your shoulder or neck alongside bleeding is an ectopic red flag.
