Weeks 1-4: Conception to Implantation
The first week of pregnancy is counted from the first day of your last menstrual period. During this time, your body is preparing for ovulation. The egg is released from the ovary and travels down the fallopian tube. If the egg is fertilized by a sperm, it will implant in the uterus lining. This is where the baby will develop and grow for the next 9 months.
