Understanding Conception and Baby Formation
What is Conception?
Conception occurs when a sperm fertilizes an egg, forming a zygote. This typically happens in the fallopian tube within 24 hours after ovulation, which is about two weeks after the first day of a woman's last menstrual period (LMP).
Timeline of Development
After conception, the zygote travels to the uterus, where it undergoes several stages of development:
| Stage | Description | Duration |
|---|---|---|
| Germinal Stage | The zygote divides and forms a blastocyst. This stage lasts until implantation. | Weeks 1-2 |
| Embryonic Stage | The blastocyst implants into the uterine lining and develops into an embryo, forming major organs. | Weeks 3-8 |
| Fetal Stage | The embryo develops into a fetus, with further growth and maturation of organs and systems. | Week 9 until birth |
Key Points
- Conception is the moment the sperm fertilizes the egg.
- The fertilized egg (zygote) travels to the uterus and implants itself, marking the start of pregnancy.
- The first signs of pregnancy, such as a missed period, typically occur about two weeks after conception.
Understanding these stages helps clarify when a baby begins to form and develop after conception.
