Your baby graduates to fetus this week

What to expect

Your baby graduated from embryo to fetus this week. They're looking less like a tadpole and more like a tiny human, with arm and leg buds becoming distinct. Those buds will form elbows and knees soon, practice kicks start in just a few weeks.

Fingers and toes are emerging, though they're still webbed for now. Eyelids are forming too, fused shut until around week 27. Inside, the liver, kidneys, and even taste buds are starting their early work.

• Growth spurt. Your baby doubles in size this week. That takes energy, hence the naps you suddenly need at 2pm.
• Moving (but you can't feel it yet). Their first muscle movements start now, like tiny twitches. You'll feel those acrobatics months later.

What to be aware of

Morning sickness might be in full swing. It's ironically named, since the nausea can strike any time. Small, frequent meals and ginger tea help many people, but don't hesitate to ask your provider about anti-nausea options if it's brutal.

• Metallic taste. That weird penny-flavor in your mouth? Blame hormones. Citrus, mints, or brushing more often can keep it at bay.
• Fatigue that hits like a truck. Your body is building a placenta. Nap when you can, even if it's just closing your eyes at your desk for 10 minutes.
• Tender breasts. They're prepping for milk production. A soft, wire-free bra helps (and ditch the underwire now to avoid clogged ducts later).

Spotting can be normal after sex or a pelvic exam (thanks to increased blood flow), but call your provider if it's heavy like a period or comes with cramps. And don't Google, just call.

What might happen

Your first ultrasound might be this week or next. Many providers schedule the "dating scan" between weeks 8–10 to check progress and confirm your due date. You'll likely see a flickering heartbeat (cue the happy tears).

• Screening conversations. Your provider may discuss genetic testing options like NIPT (a simple blood test) or CVS (an early but more invasive option). No right answer, just what fits your family.
• Symptoms log. Jot down what you're feeling this week. Patterns help providers tailor care, especially if nausea or fatigue is severe.
