What happens to the fetus after one month?

After one month of pregnancy, the fetus is about the size of a poppy seed and has begun developing essential structures. The heart starts to beat, and the neural tube, which will eventually form the brain and spinal cord, begins to develop. Major organs and systems start to take shape, and the foundations for limbs and facial features are also laid down. At this stage, the embryo is highly sensitive to environmental factors, making early prenatal care crucial.
