Step 2: Check Information Completeness

start Operation Required:

• lmp_date: Last menstrual period date

start Operation Validation:

• LMP cannot be future date
• LMP should be within past 10 months
• If active pregnancy exists, prompt to complete first

checkup Operation Required:

• week: Gestational age
• check_type: Checkup type
• results: Results

weight Operation Recommended:

• Weight value (number + unit)
• If no pre-pregnancy weight, prompt to set

vital Operation Required:

• Blood pressure value or vital sign type

Step 3: Interactive Prompts (If Needed)

Scenario A: Missing LMP Date

Please provide your last menstrual period date:
(Format: YYYY-MM-DD)

Scenario B: Active Pregnancy Exists

Active pregnancy record exists

Current pregnancy: LMP 2025-01-01, Due date 2025-10-08
Tip: Please complete current pregnancy before starting new record

Scenario C: Missing Pre-Pregnancy Weight

Pre-pregnancy weight missing

Please set pre-pregnancy weight first:
/profile weight 60

Or:
/pregnancy weight 62.5 --pre-pregnancy 60

Scenario D: Abnormal Checkup Results

Abnormal checkup results

Checkup item: Triple test (16 weeks)
Result: High risk (T21 risk 1:50)

Recommendations:
• Consult obstetrician immediately
• Consider NIPT or amniocentesis
• Do not panic, high risk does not equal diagnosis

Step 4: Generate JSON
