Anyone else like this?

I had a beautiful baby in 2014 and I am currently expecting for November 2016! This pregnancy is so different than my first one. I had some morning sickness with my first pregnancy but didn't find out until I was about 8 - 9 weeks. This pregnancy, I had a positive test at 3 weeks 6 days!! And I'm so tired all the time, and I'm nauseous day in and out. It's horrible! My boobs have already gone up a size and I'm only 4 weeks 6 days!! I can't believe how early and rank these symptoms are. Has anyone else been like this, this early? It was weird, I knew I was pregnant before my missed period too.
