Symptoms disappearing

I'm 11w3d and some of my symptoms are starting to go away. I'm no longer super tired, my nausea is pretty much gone, I don't feel bloated (but I still have a bump)... I don't want to worry, but I'm wondering if this is normal. Could it just be that I'm just getting over my 1st trimester blues? My boobs still hurt and my sense of smell is still pretty strong.
