I'm over a week late for AF. But I can't seem to get a consisted BFP. Yesterday I took a cheaper pregnancy test and thought I saw a faint line, so I went and bought the more expensive Clear blue digital test. Took it with my 4th pee of the day yesterday and got a positive result!  Then I waited until this morning and took the second one with my first pee and its Negative!! Don't know what to think! Which one is more likely to be wrong?
