Your first visit to the OB-GYN typically happens between 6 to 10 weeks of pregnancy.
What to Expect:

According to ACOG, early prenatal care is essential to monitor fetal growth and maternal health.
💊 2. Start Taking Prenatal Vitamins
If you haven’t started already, begin taking prenatal vitamins daily. These support healthy fetal development.
Essential Nutrients:
- Folic acid (400–800 mcg) – prevents neural tube defects
- Iron – supports red blood cell production
- Calcium and Vitamin D – supports bones and teeth
- DHA – supports brain development
Check labels and consult your OB-GYN for the best vitamin option.
📅 3. Know Your Due Date
Your estimated due date (EDD) is based on the first day of your last menstrual period (LMP) or the date of conception if known.
This helps schedule future ultrasounds and prenatal milestones.
