I think I feel my baby?! 12 weeks

I'll be 12 weeks tomorrow and this is my first pregnancy! The last couple days I have felt random butterfly feelings in my stomach that are quick flutters and then disappears. They happen randomly and I have been sitting or laying down for a while when I have felt them. I know it isn't gas because it definitely does not feel like gas like everyone says it should be. Sooo are these baby flutters?! My husband says I'm crazy but when I told my mom she said that it is defintely the baby!?
