Hi,
i'm not sure if they can pick up pregnancy on a test looking for anaemia. What were the other tests looking for? And did they say the other two tests were normal?
Sometimes they do a test anyway checking for pregnancy, even if you don't tell them you could be pregnant. Have you taken a pregnancy test yet?
Why do you not want the doctors to know that you might be pregnant?
It might just be that you are suffering from iron defificency anaemia - I have anaemia at the moment - it always gives me feelings of nausea, tiredness, and dizzyness etc.
Let us know how you get on.
Take care.
