Your baby this week
Your baby is about the size of a grape. The graduation matters: the embryonic period — when all the major structures are built — is complete, and the fetal period of growth and fine-tuning has begun. The heart is dividing into four chambers, tiny teeth and taste buds are forming, and the elbows can bend. Your baby moves now, though it will be many weeks before you feel it.
Your body & symptoms: the fatigue peak
For many moms, weeks 9–10 are the summit of first-trimester tiredness and nausea. Blame the placenta under construction and hormone levels near their highest. The hopeful part: the placenta will soon take over hormone production, and most moms feel the tide turn as the first trimester closes. If you're in the hardest weeks right now — relief genuinely is coming.
Your first prenatal visit: what really happens
If your first visit lands this week, expect a longer appointment: your medical history, blood pressure, weight, blood tests (blood type, iron, immunity and screening for infections), a urine test, and a discussion of screening options for the weeks ahead. You may also discuss diet, exercise and any medications. It's a lot of information — bring a notebook or your phone, and your questions.
Riding out the peak weeks
Eat what you can, rest when you can, lower every bar that can be lowered. This is a season, not a standard. Frozen meals, paper plates and early bedtimes are legitimate strategies.
⚠️ Warning signs — call your doctor the same day
Heavy bleeding · severe or worsening pain · fainting · fever · vomiting that prevents you keeping fluids down for a day. If something feels wrong, making the call is always the right move.
