Initial sway, total sway, and sway velocity (see figure for description of variables) are significantly less during the third trimester than during the second trimester and when compared to non-pregnant women. These biomechanical characteristics are possible reasons why falls are more prevalent during the second trimester during pregnancy.
Signs and symptoms of pregnancy are common, benign conditions that result from the changes to the body that occur during pregnancy.

A first-of-its-kind case study has highlighted the ways in which the brain changes throughout pregnancy, including decreases in gray matter volume, and increases in white matter.
This increase in size and weight of the uterus puts stress on the ligament that holds it, causing it to stretch. During physical exertion or sudden movements, the ligament is overly stretched, causing pain. Varicosities, [7] e.g. enlargement of the blood vessels of the round ligament can occur during pregnancy, causing pain and swelling. The ...
Placenta previa is primarily diagnosed by ultrasound, either during a routine examination or following an episode of abnormal vaginal bleeding, often in the second trimester of pregnancy. Most diagnosis of placenta previa occurs during the second-trimester. [citation needed]
Laboratory based measures during the second trimester show a further decrease in total sleep time, slow-wave sleep and sleep quality. [1] [2] No changes in REM sleep have been observed. [1] Fetal movements, uterine contractions, musculoskeletal discomfort and rhinitis and nasal congestion account for the physiological factors influencing sleep. [2]
