Pregnancy test

Hi guys! I am 7 days late on my period and peeing like a trooper! I did a "confirm" pregnancy test and it showed a faint line of positive! I've then read reviews saying they are a complete waste of time and false positive comes up! It's late at night so I can't pop out to get a better brand as my husband will get suspicious and I don't want to get his hopes up as we have been trying for 1.5 years! Has anyone got any info on this brand?
