A Comparative Analysis of Stretching Exercise and Pregnancy Exercise on Sleep Quality in Pregnancy: A Quasi Experiment

The goal of this clinical trial is to learn whether pregnancy exercise or stretching exercise can improve sleep quality in third trimester pregnant women who experience sleep disturbances. The main questions it aims to answer are: * Does traditional pregnancy exercise improve sleep quality more effectively than stretching exercise? * Does either type of exercise reduce anxiety levels that may affect sleep? Researchers will compare a pregnancy exercise group with a stretching exercise group to see whether one approach leads to better sleep quality. Participants will: * Attend guided exercise sessions twice a week for three weeks * Complete questionnaires about sleep quality, anxiety, and physical activity * Have basic health measurements taken (blood pressure, weight, height) before and after the program This study hopes to show whether moderate exercise can help pregnant women sleep better during the third trimester.
