If there is a line,no ,matter how faded,then I would say you are pregnant.I did this when pregnant with my son,he was an IVF baby and so for two weeks we didnt know whether it had worked or not,and so I did a test 2 days before going to the hospital for their official test,and I also had a line so faint I could barely see it,and thought that it hasn't worked.But 2 days later I had it confirmed that I was indeed expecting.
So I think I can tentatively say - congratulations!!!!
