Anyone experience this and have a healthy pregnancy?

I am currently 10 weeks pregnant. I started experiencing pregnancy symptoms right away, before I could even test, but they've been very mild this whole time (occasional nausea, no vomiting, & sore breasts). Over the last few days, maybe as long as the past week, my symptoms have reduced noticeably. I know symptoms can come and go (and mine have from time to time), but I've never had this many days in a row where I wasn't really feeling pregnant. I had an ultrasound at 7 weeks with a healthy little bean with a healthy heartbeat, but I'm worried about my reduction in symptoms bc I know that can sometimes indicate a miscarriage is coming.

Has anyone else experienced symptom reduction as early as 9-10 weeks and still had a healthy baby and pregnancy? I am anxiously awaiting my next OB appointment this Thursday to hopefully hear the heartbeat and get some reassurance!
