While your first sign of pregnancy might have been a missed period, you can expect several other physical changes in the coming weeks, including: Tender, swollen breasts. Soon after conception, hormonal changes might make your breasts sensitive or sore. The discomfort will likely decrease after a few weeks as your body adjusts to hormonal changes. Nausea with or without vomiting. Morning sickness, which can strike at any time of the day or night, often begins one month after you become pregnant. This might be due to rising hormone levels. To help relieve nausea, avoid having an empty stomach. Eat slowly and in small amounts every one to two hours.
