nausea disappeared at 8 weeks

Hi! I know this has probably been asked 100 times here but I’m a little paranoid/worried.

My nausea hit on week 6 quite horribly (although I was thankful for it) and now at week 8 (today is 8+3) it seems to have completely disappeared. I still have very sore breasts.

Is this a bad sign? I have read that lost of symptoms can be a sign of missed miscarriage? My scan isn’t until next Tuesday :(

any stories of something similar happen with happy endings?
