What does it mean to have your blood test for pregnancy come back Indeterminate?

It means that you don't have enough hCG in your blood yet to be considered pregnant, but you also have too much for them to give you the 'not pregnant' sign.

You might have an ectopic pregnancy or an early pregnancy, but not always, so try not to stress too much about it, as hard as it can be. (I am going through this right now.)

Doctors have different cut offs for what is 'pregnant' vs. 'indeterminate' vs 'negative', so you could ask for a number, if the test was quantitative (many tests now are).
