Help!

Up until today I've had pretty bad nausea and sore breasts (since week 5). I'm 6w5d and the last two days I noticed my nausea wasn't as bad. I keep feeling my breasts to see if they're sore and I think they're less sore. I miscarried at 7 weeks with my only other pregnancy and loss of symptoms was my first symptom of miscarriage. 
Has anyone had a loss of symptoms this early and had it lead to to nothing? Like, is it possible to lose symptoms and still be progressing where I need to be?
