Your baby this week
Your baby is now about the size of a kumquat or a prune (approximately 31 mm or 1.2 inches from crown to rump) and weighs about 4 grams. This week marks a critical transition: the embryonic period is officially over, and all vital organs have formed — from here on out, they will grow and mature but no new organs will develop. Bones are beginning to harden through a process called ossification, replacing the soft cartilage with actual bone tissue. Tiny fingers and toes have separated and are no longer webbed, and small nails are starting to grow. The brain is producing an incredible 250,000 new neurons every minute. If you could peek inside, you'd see your baby swallowing amniotic fluid, kicking, stretching, and even hiccupping — all movements too small to feel but clearly visible on ultrasound.
How you may feel
Visible veins may appear across your breasts, abdomen, and legs as your blood volume has increased by about 50% to support the growing fetus and placenta. You might experience mild headaches, caused by hormonal changes, increased blood volume, and possibly dehydration or caffeine reduction. Round ligament pain — brief, sharp twinges in your lower abdomen or groin — may begin as the ligaments supporting your uterus start to stretch. Your uterus is now about the size of a large orange and may be palpable just above the pubic bone. Many women begin to feel slightly less nauseous as hCG levels start to plateau — the end of first-trimester misery may finally be in sight. Emotional ups and downs continue, and you may worry about the health of the baby, especially as genetic screening tests approach.
Common symptoms
- Nausea may start to ease slightly, though it lingers for some women.
- Visible veins on your breasts and abdomen as blood volume increases by 30–50%.
- Round ligament twinges — brief, sharp pains in your lower abdomen when you move.
This week's tips
Drink at least 8-10 glasses (about 2.3 liters) of water daily — adequate hydration helps prevent headaches, constipation, urinary tract infections, and supports the increased blood volume your body needs. If you haven't had your first prenatal visit yet, schedule it now — blood type, Rh factor, anemia screening, STI testing, and other important baseline labs should be completed early. Discuss genetic screening options (NIPT, NT scan, first-trimester combined screening) with your healthcare provider to make an informed decision about testing. Incorporate calcium-rich foods into your diet (dairy products, fortified plant milks, leafy greens, almonds) — your baby's bones are actively hardening and drawing calcium from your body. Avoid changing cat litter, gardening without gloves, and eating undercooked meat to minimize toxoplasmosis risk.
Eating well
- Incorporate lean red meat or iron-fortified cereals to prevent early anemia.
- Eat calcium-rich snacks like almonds, cheese cubes, and yogurt parfaits.
- Try dried apricots and dates for iron, fiber, and a natural energy boost.
Nutrition focus
- Continue prenatal vitamins consistently — baby's organs are rapidly developing.
- Omega-3 (DHA 200–300 mg/day) remains critical for brain and retina formation.
Everyday wellbeing
- Schedule your first-trimester screening (nuchal translucency) for weeks 11–13.
- Light strength training with dumbbells (under 10 lbs) is safe and beneficial.
- Elevate your head with an extra pillow if heartburn disrupts sleep.
For your partner
Place water bottles in every room of the house — on the nightstand, kitchen counter, living room side table, and in her bag — so staying hydrated becomes effortless for her. Accompany her to prenatal appointments whenever possible; being present shows commitment and helps you both stay informed about the baby's health. If genetic screening discussions come up, approach them as a team — listen to her concerns, do your own research from reliable sources, and make decisions together. Start looking into parental leave policies at your workplace and understand your options. This is also a good time to check that your home environment is safe: secure heavy furniture to walls, check smoke detectors, and begin thinking about any baby-proofing that will be needed down the road.
Signs to mention to your provider
- Persistent vomiting causing weight loss of 5% or more needs medical treatment.
- Painful urination with fever may indicate a kidney infection — see your doctor today.
- Sudden disappearance of all pregnancy symptoms may warrant an ultrasound check.
