Let’s dive in!

1. Confirm Your Pregnancy:
Before anything else, take a home pregnancy test after a missed period.
For accuracy:
– Test first thing in the morning (highest hCG levels).
– If positive, schedule a blood test or ultrasound with your doctor to confirm.
Early signs of pregnancy include fatigue, nausea, sore breasts, and frequent urination.
2. Choose a Healthcare Provider:
Your OB-GYN, midwife, or family doctor will guide you through prenatal care. Consider:
- Hospital vs. birth center preferences
- Insurance coverage
- Provider’s approach (e.g., natural birth-friendly, high-risk expertise)
Pro Tip: Ask for recommendations in local mom groups or read reviews!
3. Start Prenatal Vitamins Immediately:
Key nutrients for early pregnancy:
- Folic acid (400–800 mcg) – Prevents neural tube defects.
- Iron – Supports increased blood volume.
- DHA (Omega-3) – Aids baby’s brain development.
Best prenatal vitamins often include these—check labels or ask your doctor.
4. Schedule Your First Prenatal Visit:
Your first prenatal appointment (usually around week 8) may include:
- A dating ultrasound to estimate due date.
- Blood tests (checking hCG, iron, immunity, STIs).
- Discussion of family medical history.
Note: Write down questions beforehand—this visit is info-heavy!
