What are some early pregnancy symptoms y'all have had?!

Lauren
I've just been feeling off lately...today I slept over 18 hours, I can't get enough sleep! My stomach has been upset lately but no vomiting yet! I'm really bloated and have gained about 5 pounds of water weight. I have also had a headache every day for the past 3 days. Could I be pregnant?? Are these some pregnancy symptoms anyone else has had?? What are some of y'all's early pregnancy symptoms?!
