Honestly it doesn't sounds good. The only way you'll know if you are miscarrying is to get another hcg draw to see if your levels are doubling every 48-72 hours or decreasing.
They didn't tell you if u had a MC at the beginning of the pregnancy I had bleeding they told me maybe it was because inplantation now I am 4 month's n still bleed but now they told me I have a low line placentaand that's what's causing that but I never had heavy bleeding just spotting hope everything turns out OK
either you are very early in your pregnancy or you miscarried
