What are the most common symptons that means pregnancy? i have read online, and i seem to have none, but i'm still concerned as to if its my period.

Are due to hormones: One can just do a home pregnancy test, and not worry about symptoms. Common early pregnancy symptoms include some nausea (with or without vomiting), some fatigue (feeling less energetic), a sharper or stronger sense of smell, mild soreness and swelling of the breasts, and maybe some food aversions or cravings. These symptoms are due to quickly rising hormone levels.
