Is your period late? If so, take a home pregnancy test with your first morning urine for best accuracy. If it comes up negative then wait a few days to a week and if your period still hasn't started take another test and/or call your doctor. It's hard to know sometimes if you are pregnant just by symptoms because pms symptoms and pregnancy symptoms are very similar. Some of the symptoms of pregnancy include sore, tender breasts, bloating, pms-like cramping, fatigue and upset stomach. I hope that helps you out some.
