10 week nausea

Melissa
So I am 10 1/2 weeks and all of a sudden my nausea has gotten a little better. Not totally better. I am also not as tender in the breast area. 
I had a miscarriage at 11 weeks my last pregnancy so I'm super nervous about this week and next. Could I just be reading too much into this? Anyone have any experience with nausea subsiding around 10-11 weeks?
Thanks! :)
