Pregnancy symptoms can start to appear very early, often as soon as one to two weeks after conception. Some of the earliest signs include breast tenderness, fatigue, spotting or light cramping (implantation bleeding), and heightened sensitivity to smells. Nausea ("morning sickness") can begin around the fourth to sixth week after conception, but can vary among individuals. A missed period is typically one of the first clear signs of pregnancy, usually noticeable around four weeks after the last menstrual period. However, the timing and presence of symptoms can vary greatly between individuals, with some feeling symptoms very early and others not until later weeks or even until a pregnancy test confirms it.
