Has anyone else just woken up one day and all symptoms are gone? (Yes I know this usually doesnt mean anything, but it is still concerning)

I am 8 weeks 3 days and I have had severe swollen sore breats and occasional nausea but enough that I noticed it every day. I woke up today and feel completely normal. I miscarried in November and I am just concerned. I have my first US on Thursday but recently called and left a message to see if I can get in today, just to ease my mind.
