Pouring blood at 9 weeks

Hi all, this is my third pregnancy is 6 months (5 week and 12 week losses). I am 29 and healthy. Doctor thought I may just need a progesterone supplement and baby aspirin, which I have been taking since my d&c. We got our second ultrasound a couple days ago and baby was perfectly healthy and growing, but then just 24 hours later I started pouring very thin blood for hours. No cramping or clots. It has tapered off but hasn't stopped. Of course it is a holiday weekend, so I can't go to the doctor until Tuesday. Is there ANY WAY this isn't a miscarriage? I am so done with pregnancy.
