is this normal?

I found out recently  I am finally pregnant again. I have my doctors appointments coming up and I'm super anxious. However my symptoms are super calm, nothing like my first. No extreme morning sickness, very little fatigue, I have very frequent bathroom breaks and always needing to snack more than usual. I was possibly having signs prior to today because there was the fatigue part where it was hard to drive, cold like symptoms, headaches and dizziness. I still had a period though so I'm not sure. 
My question is should I worry?
