It shouldn't THC (the psychoactive chemical in marijuana) works by mimicking neurotransmitters in your brain. It is broken down into metabolites and remains in the blood for days to weeks, depending how often marijuana is used. Home pregnancy tests test for human chorionic gonadotropin, which is a hormone released once implantation of the egg occurs. I see no reason as to why THC metabolites would affect a pregnancy test. Pregnancy tests have also been known to give false positives too, so taking two is always a good idea.
