Real, evidence-based guidance for exactly where you are right now.
Baby Development
The end of the first trimester. The placenta has now taken over as the primary source of pregnancy hormones (previously produced by the corpus luteum) — this shift is part of why nausea often improves around now.
Your Body This Week
Energy is often improving; a small bump may be starting to show, though this varies widely.
Diet
Continue a varied, nutrient-dense diet.
Supplements
Continue your folic-acid-containing prenatal vitamin, and confirm with your doctor that it also contains adequate iron, calcium, and vitamin D for the trimesters ahead.¹
Tests
First-trimester screening results, if done, are typically discussed around now.
Vaccinations
None specific to this week — the routinely recommended pregnancy vaccines (Tdap, RSV) are timed for later in pregnancy, not now.⁵
Exercise
Continue or gradually increase moderate activity as energy improves, per your doctor's guidance.²
Red Flags — When to Call Your Doctor
Heavy bleeding, severe pain, or fever warrants urgent medical attention.
Doctor Visits
Routine follow-up; many providers discuss the coming anomaly scan (around 18-22 weeks) around now.
Mental Health
Reaching the end of the first trimester is a real, meaningful milestone for many, often bringing genuine relief and renewed energy for the pregnancy ahead.
Frequently Asked Questions
Why did my nausea improve around now?
The placenta has taken over hormone production from the corpus luteum, and hCG levels — which are linked to nausea — typically peak around weeks 9-10 and decline afterward. This shift is a real, physiological explanation, not a coincidence.
