Hi, I have done UPT twice at home in a gap of three days. Earlier it was a faint positive line then secondly line became little darker than before. I went to consult the doctor as i have been earlier diagnosed with PCOD, she asked me to go for HCG test, my levels were 45, but she is not clear if i am pregnant. Can you please clear this out for me. Also she has asked me to check HCG again.
