What were your first signs of pregnancy?

I'm just wondering because so far 
-I keep having this feeling telling me to buy a test, but so far all negative. But still in the back of my mind I keep thinking I need one (this could also be a sign I'm crazy lol)
-I've had a couple of very weird dreams 
-my face has broken out. As soon as some acne begins to heal up, more pops up 
-my breasts are swollen 
-I feel like no matter what I eat, it doesn't keep me full. 
I could be pregnant or I could be an insane girl that over-eats haha. 
Any help would be appreciated ;)
