Frequently asked questions
How is gestational age calculated in the Ethiopian calendar?
Gestational age starts counting from the first day of your Last Menstrual Period (LMP) in Ethiopian calendar dates. The total days elapsed divided by 7 provides your exact completed gestational weeks and remaining days.
What are the three pregnancy trimesters in weeks?
The first trimester spans from week 1 through week 12. The second trimester covers weeks 13 through 27. The third trimester starts at week 28 and continues through delivery (weeks 37 to 42).
When is the recommended schedule for Antenatal Care (ANC) visits in Ethiopia?
Under Ethiopian Federal Ministry of Health (FMoH) guidelines, at least 4 to 8 ANC contacts are recommended: 1st contact before 12 weeks, followed by contacts at 20, 26, 30, 34, 36, 38, and 40 weeks.
What is the difference between gestational age and fetal age?
Gestational age is calculated from the first day of your LMP (about 2 weeks before conception), while fetal age is the actual biological age of the developing fetus.
