Pregnancy symptoms can start to appear as early as one to two weeks after conception, often before a missed period. Early signs include tender or swollen breasts, fatigue, nausea (morning sickness), frequent urination, and missed periods. However, the visible "baby bump" of pregnancy typically begins to show later, generally during the second trimester between 16 to 20 weeks. For first-time pregnancies, showing may start closer to the middle or end of the second trimester, while women who have been pregnant before may show earlier due to stretched abdominal muscles. Some women might notice early changes by the end of the first trimester or beginning of the second trimester. Overall, while bodily symptoms start quite early, the physical appearance of pregnancy usually becomes noticeable months into the pregnancy, commonly around 12 weeks or later depending on individual factors.
