feeling super confused...

Nikaya
so I've had some on and off spotting since Friday, so I had blood drawin yesterday and they called today and said it looks as though I'm miscarrying and that would should see my levels go down, then let l me go with out answering any questions and so I decided to call the doctors office because I was confused because the nurse who drew my blood said they had to do 2 draws to see if the levels double or not so I called and she said it was my 1st draw and that my levels were in the 3000's and that we wouldn't know til u have my blood draw again tomorrow... so I'm so lost as to why that nurse called me... 😢
