Lessened symptoms in week 9?

Katie
I'm in my 9th week.  For the last few weeks I've had mild nausea pretty consistently (at least once a day) and extremely sore breasts.  The last couple of days, I've not had any and my breasts seem less sore.  I had a missed MC earlier this year so I'm a bit paranoid....is this normal?  Have any of you experienced this and everything was fine?
