First pregnancy symptoms disappeared

So I am 8w6days as of today and most of the few symptoms I actually had have disappeared. I was experiencing some light nausea in the mornings or afternoons (never vomiting), had some aversions to food for a while and just wanted plain things, and of course I was sleeping all tne time. But my boobs have never been sore and all my symptoms seem to be rather light. I don’t want to complain but over the past week it seems that all of them have disappeared and I am petrified something is wrong.

I had my first sonogram at 7w2d and we did see a heartbeat so I was reassured for a while, but now I feel like something has stopped. I know I am being paranoid but has anyone else experienced this or have any tips for staying positive?
