Help me please

So yesterday I started spotting and came to the ER. They did a pelvic exam and my cervix was closed. Today I came back because the bleeding started getting a little heavier. Since I been here the bleeding has went back down and almost dropped but they told me my HCG levels has dropped and I may be facing a miscarriage. I’m 6 weeks tomorrow. I have a ultrasound scheduled. Is it possible my levels can go back up. Or is this it and I will just have to cohoe that I may lose my baby.
