HCG blood test

Brooklyn

So the range for the blood test where I get it done is 0-3 for negative. The last 2 tests I’ve had done came back at 0. Today it came back at 3. My OB ordered another blood test to be done on Friday to see if it doubles. What do you think???? It’s still technically negative so I don’t want to get my hopes up but it’s always come back at 0 until today…..
