First OB appointment I'm so nervous

Kat
Today is our first Ob appointment and I'm crazy nervous, what if something isn't right..I know it's out of my control..but just the thought makes me feel uneasy..anyone else felt this way or feel this way? I'm nauseous on and off, constipated, so freaking sleepy, cramping off and on...does this sound normal and ok...sorry y'all just freaking out I guess
