Look for the signs: The early signs include some nausea (with or without vomiting), some fatigue (feeling less energetic), a sharper or stronger sense of smell, mild soreness or swelling of her breasts, and maybe some food aversions and cravings. If the signs occur, one can do a home urine pregnancy test. If worried about pregnancy, one can do a pregnancy test even without signs of pregnancy.
