I don't think your boyfriends sleeping habits have anything to do with you being pregnant or not. Your symptoms of pregnancy will usually appear anywhere from the first week of your expected period to 1-2 weeks after your first week of expected period. Your first signs of pregnancy most commonly include missed period, tender/swollen breasts, change in color of the breasts, fatigue, nausea/vomiting, increased sense of smell, and weight gain.
