I Wonder if Something is Wrong with Me?

So... for the past three days I have noticed that my heart starts beating faster for a couple seconds several times throughout the day. It's weird. I'm not sure if that is what a heart palpitation is or whatever it's called, or what?! It's like how I feel when I get nervous. Except I haven't been nervous lately. At least not that I know of. It's a little weird. I guess I'll try to pay attention this weekend and see if I notice it. Maybe it is work stress. Even though I don't really let work stress me out much. So I don't know why it'd be causing my heart to speed up like that.

Either way. It is freaky.
