Anxious like woah!

I have my first appt with the obgyn on Monday and I'm just so anxious. This is my first pregnancy and I'm just so afraid of doing something wrong... I was doing the math tonight and I could either be just about 12 weeks, or a little over 7. All I can eat right now is for the most part fruits and veggies, toast on some days, and candy. I really need to find a way to start being able to stomach some sort of protein... 
So what do you think? 7 weeks, or closer to 12:
