If you have a positive pregnancy test result and are considering an abortion, you have the right to have all of your questions answered before making any decisions. This fetal development information will allow you to understand the growth of your baby through each stage of pregnancy. The weeks of pregnancy are determined from the first day of your last period.

Stages of Fetal Development

First Trimester
  • Week 4 - Positive pregnancy test
