This document discusses the signs and symptoms of pregnancy over three stages: early, mid, and late pregnancy. In early pregnancy, subjective symptoms include amenorrhea, morning sickness, and breast tenderness. Objective signs are uterine enlargement and positive Hegar's sign between 6-10 weeks. Mid-pregnancy signs are quickening felt between 16-18 weeks, linea nigra rash at 20 weeks, and fundal height measuring appropriately. Late pregnancy is marked by darkening of linea nigra and breasts, prominent stretch marks, thick breast discharge, fetal movement palpation at 20 weeks, and normal fetal heart rate between 110-160 bpm.
