symptoms subsiding week 6

Alyssa
Has anyone had their symptoms come and go? I feel like I was pretty miserable up to now and woke up yesterday feeling great.  So what do I do?  Freak out.
I still have some like sore boobs but not as bad as before.  Mainly I feel like a fog has lifted, but I'm wondering if that's just me getting used to that I'm pregnant.  I'm a first time mother. Also I have general anxiety- nothing I can't control (no meds needed) but sometimes it flares up:)
Thanks for any advice or your experiences
