Weeks 1-4: This is technically before and during conception. By week 4, the blastocyst implants into the uterine lining.
Weeks 8-12: Most women have their first prenatal appointment and “Dating Scan” during this window. The fetal heartbeat can usually be seen on ultrasound by week 7 or 8.
Week 20: The “Anatomy Scan” occurs. This is a detailed ultrasound to check the baby’s growth and organ development.
Week 24: This is considered the “limit of viability,” meaning the baby has a chance of survival if born prematurely, thanks to modern NICU care.
Weeks 37-40: You are considered “Early Term” at 37 weeks and “Full Term” at 39 weeks.
