6 weeks not many symptoms?

Cara • Expecting our first baby Jan 1st 2016! Married my best friend after 8 years together 10/10/14.
I'm about 6 weeks and I don't have much going on. Is this normal? When I found out I was pregnant I had increased clear/white discharge, gas, and felt dizzy. That was 4 weeks ago. Now that has all stopped. I haven't felt nauseous at all. I only have little cramps occasionally usually more at night and sore around the outside of my breasts. I'm nervous!
