Pregnancy symptoms can start very early, often as soon as one to two weeks after conception. Some of the earliest symptoms include breast tenderness, fatigue, mild cramping, spotting (implantation bleeding), heightened sense of smell, and bloating. The most reliable early sign is typically a missed period, which usually occurs around 4 weeks into pregnancy. Symptoms like nausea ("morning sickness") often start around 4 to 6 weeks but can vary widely among individuals. Some women may notice symptoms even before missing a period, while others may not experience any symptoms until later in the first trimester.
