Do symptoms come and go?

Hey ladies. I'm 7+5 today and I woke up without painful breasts this morning. I've been sleeping in a sports bra ever since before I found out I was even pregnant. My boobs have been really sensitive and sore....today, nothing. Does this come and go? Also I never have really had any morning sickness maybe slight nausea but that's it. I'm starring to worry since my symptoms seem to be fading.
