Hcg levels?

Mystery

Im very new to this whole pregnancy stuff and keep freaking myself out over and over

Anyways, initially i was maybe 4ish weeks or a little less so the drs said and my hcg levels were at 400, is this good?

I get an ultrasound on the 22nd and im terrified something may be wrong!

Let it be known i have no cramping or anything like that but i do have an ovarian cyst.
