Welp...probably pregnant...

It's been two moths since my last cycle and I had the nasty before I was supposed to bleed and only got a tiny spotting when I would've had my period. Now I get nauseated if I eat what I used to and my tastes are changing...could I be pregnant? I plan on going to the doctors to make certain that I am or not. I'm not sure if I should be excited or terrified.
