Getting hopeless 😔

TK

I ovulated on 6th of June. Then I found out I was pregnant June 16. I went to the hospital June 25 because I was spotting and cramping they said my hCG levels were at 2500 but they couldn’t see anything on the ultrasound . I went back for another beta on the 30th of June which turned out to be 10,400. They still couldn’t find anything I have no idea what to think because the doctors haven’t really told me much should I remain hopeful? I am currently supposed to be seven weeks two days pregnant.
