Should I be concerned?

I just found out Friday I am pregnant. I have not had a period since February. I had no sickness or nausea. Just a little fatigue and frequently peeing. Like a lot! My lower abdomen was hard and getting good harder and I couldn't lay on my back without feeling like my bladder was gonna bust. Lol I took 2 test and they came back positive but is it commen to not feel any sickness or nausea? I'm guessing I'm 12 weeks. Luckily I go to the doctor on the 9th but I'm almost questioning if I am pregnant. Advice?
