Symptoms

This is my first pregnancy and I was just wondering if it was normal to not really have any symptoms yet. My boobs get really sore but it's on and off not continuous. And I got really nauseous all of a sudden for the first time today. Plus the fatigue. But I've been reading posts on here about women 6 weeks pregnant and having all these terrible symptoms while mine haven't seemed as bad as what I've read. It keeps making me want to take another test but I've took 3 which have all came out positive.
