If you are pregnant, it is normal to feel curious and worried at the same time. Some weeks you feel symptoms strongly. Some weeks you feel almost nothing. That is when doubts start. Is everything growing fine? Is your scan too far away? Are your symptoms normal? This is why many women search how your baby develops week to week and want clear answers.

Pregnancy is usually divided into three trimesters, and each trimester has a clear development focus.
| Trimester | Weeks | What Develops The Most |
| First trimester | 1 to 12 | Basic body structure, early organs, early heartbeat activity. |
| Second trimester | 13 to 27 | Growth, movement, stronger bones, detailed scan milestones. |
| Third trimester | 28 to 40 | Weight gain, lung maturity, brain growth, birth readiness. |
