I took a home pregnancy test and it came back positive, yet a week later I went to the hospital for a ultrasound and the sonographer said she could'nt see anything she said it could be that it's a very early pregnancy so I had a blood test. The following day I contacted the hospital who told me that there was no pregnancy there and she would expect me to bleed in the next week! Its been two weeks and 2 negative tests later however, I'm still waitng its been nearly 8 weeks since my last period. I'm taking immunosuppressant drugs. Could this be the reason for my negative readings? Could I be pregnant?

Can I ask have you had any spotting or brown discharge?

No nothing at all.
