Beyond Worried

Alicia
I'm 9w1d and I've noticed in the last few days my symptoms have early completely gone away. I used to be nauseous, extremely tired, breast tenderness, sore nipples, etc. 
Now I have none of that. I don't know if something is wrong or if this is a missed miscarriage but I need some advice. I go in next week for an ultrasound but I'm panicking over here and that seems like a lifetime away.
