Week 5: The Neural Foundation
Baby is about the size of Sesame seed (2mm)
The embryonic period begins. The neural tube—precursor to brain and spinal cord—begins forming. The primitive heart begins as two tiny tubes. This is the most critical period for folic acid.
Progesterone surges, causing significant fatigue, breast tenderness, and mood changes. hCG is doubling every 48-72 hours. Morning sickness may begin.
What is important now
Folic acid is critical NOW—the neural tube closes by Week 6. Confirm prenatal vitamin has 400-800mcg.
Common symptoms
- severe abdominal pain one sided — emergency evaluation
- heavy bleeding — contact provider urgently

Mindfulness
The first trimester can feel isolating, especially before you've told people.
“Right now, microscopic miracles are unfolding. Rest when you need to.”
Your timeline.
Week 6
Next week- routine
Checkpoint 1 — Mutterpass may be issued upon heartbeat confirmation
Week 19
In 14 weeks- routineWeeks 19–22
Checkpoint 2 — Screening Ultrasound
Choice between a basic biometric scan or detailed organ scan. Measures head circumference, abdominal circumference, femur length, and checks placental position.
GoalAssess fetal anatomy and growth, check for structural abnormalities, and verify placental location.
Week 28
In 23 weeks- routine
Checkpoint 1 — GDM screening
- routine
Checkpoint 2 — Rhogam if Rh-negative
Week 29
In 24 weeks- routineWeeks 29–32
Checkpoint 3 — Screening Ultrasound
Third and final routine ultrasound. Assesses fetal growth, position (cephalic/breech), amniotic fluid volume, and placental function.
GoalConfirm appropriate growth trajectory and baby's position for delivery planning.
Week 35
In 30 weeks- self pay igelWeeks 35–37
Checkpoint 1 — GBS Testing — Self-pay/IGeL
Rectovaginal swab to screen for Group B Streptococcus colonization. If positive, IV antibiotics are given during labor to prevent neonatal infection.
GoalIdentify GBS carriers to enable prophylactic treatment during delivery.
Safety: One-sided severe pain with bleeding requires immediate evaluation to rule out ectopic pregnancy.
