At the hospital, again

Went to my first ob appointment and they told me I'm considered too "high risk" and a liability because of the bleeding and my blood condition. They also said they did a urine pregnancy test and it was negative, but I did a first response YESTERDAY and it was positive! So they told me I need to come back to the ER and if I'm still pregnant I'll have to see a high risk doctor to monitor the rest of my pregnancy. I'm worried sick and just want some answers 😭
