Disappearing pregnancy symptoms

I woke up today feeling completely normal with no symptoms at all. I'm 6 weeks and 2 days pregnant today, but my breasts and nipples are no longer sore. I never really experienced morning sickness before but my breasts and nipples were extremely sore before. Now, nothing. I'm not bleeding, so I don't know what to do. Last time I had a miscarriage, my body still felt pregnant before it expelled my early pregnancy. I'm really worried.
