Normal or not?

So some days my symptoms are terrible. Like extreme waves of nausea (no vomitting), huger, gas, cramps, bloating, frequent urination, tender boobs, etc. Then some days I feel fine, like I'm not even pregnant. It's like all those symptoms become minimal and are rarely there and then some days they are pretty extreme. 
I'm 5 weeks today. I'm not sure if this is normal or not.
