Symptoms come and go?

Hi ladies,
I am 7 weeks 5 days, and things seem to be going well with my last scan at 7 weeks 2 days showing a hb of 164 bpm (my previous two pregnancies ended in m/c). 
Is anyone else having symptoms come and go?  I have had sore boobs, but today they are fine, and my very mild nausea/food aversions are gone today too. 
I'm actually hoping they all come back so I can feel assured the pregnancy is going ok!  (I am sure this has been covered already but I couldn't find anywhere)
