What could this mean?

I took a pregnancy test on 1/30/2020 and within a minute, both said positive. I was suppose to get on my period the very last week of January so when I was late, (which I never am) I decided to take a test. I haven’t been to the doctors yet to figure out how many weeks I am but I did go to the hospital 2/3/2020 morning because I spotting brown/ light pink. This is my first pregnancy so I wanted to make sure everything is okay. They sent me home and asked me to come back in 48 hours to redo my pregnancy count. I went back the same day because the bleeding is heavier, now it’s like period blood/flow. They still can’t tell me what’s going on until 48 hours to redo my pregnancy count. I’m not cramping, I’m not under any pain, I’m just bleeding. I’m scared I might be having a miscarriage.
