The fetus responds to light shone on the belly. Air sacs (alveoli) in the lungs are forming. Spine is getting stronger with 150 joints, 33 rings, and 1,000 ligaments.

The growth rate during the second trimester is steady and consistent, with your baby gaining length and developing increasingly sophisticated body systems.

Emotionally, week 26 can bring its own set of experiences. Third trimester approaching brings a mix of excitement and anxiety. Some women feel overwhelmed by remaining preparations. Emotional sensitivity may increase. Growing eagerness to meet the baby. These emotional shifts are influenced by hormonal changes, physical discomfort, sleep disruption, and the psychological weight of preparing for parenthood. The second trimester often brings improved mood and energy, though emotional ups and downs remain a normal part of the experience.

Women who have been pregnant before may recognize these symptoms more readily, though every pregnancy is different and symptoms that were present in one pregnancy may be absent in another (and vice versa). Your body has its own unique way of responding to pregnancy.
