Is 10dpo too early to feel nauseous?

Valerie
Yesterday morning 10dpo, i felt absolutely nauseous. Hasnt really gone away. After i eat, i almost immediately feel sick to my stomach. If i drink water, or juice, i feel sick. I cant keep anything down. Could this be morning sickness? My friend says she had m/s around 2 weeks with her most recent pregnancy? Is that normal? Or am i going crazy?
