Symptoms disappeared?

MommaSmitty
I'm six weeks and five days and the only real symptoms I've had so far have been tiredness weeks three and four (which then went away for the most part) and then nausea that went from intermittent to continuous weeks five and six, but about six weeks three days has basically gone away as well. I still have strong food aversions but overall feel normal outside of some random burping. I don't need to be worried that things have calmed down, right? (This is me rationalizing my crazy, lol) our first ultrasound is Thursday and now I'm worried something is wrong even though I'm sure that's unnecessary.
