Unsure miscarriage ?

Alexandra

So last Friday I had a blood test to confirm these positive pregnancy test I was getting last week. They called me on Friday and did tell me my blood was positive. On top of all this the pregnancy symptoms have been going crazy nauseous one minute hormonal the next. Come Monday this week I started spotting bright red and light pink blood. I went into the emergency room because I’ve had a miscarriage before m and I was worried. They did an ultrasound and blood test and both were negative. I’m not sure if they were trying to tell me I was never pregnant or what but I am so confused. How is is right before the weekend the doctors office calls to tell me I’m pregnant again then Monday comes around and I’m bleeding and “was never pregnant”. I don’t see my OB till Friday can someone please let me know what u guys think. I had a miscarriage my very first pregnancy but it was really bad and I started to hemorrhage and almost died. This is heavy bleeding with borderline intense cramping.
