oh, i forgot to mention one line is negative, two pink lines is positive if you buy that one.
buy the first response urine stick, it can detect pregnancy 5 days before your period is due so you don't have to wait until you think your late. My daughter took two and she was only two weeks pregnant at the time. they both had two very pink lines across it which is positive. goodluck
Well false positives are rare, and false negatives, not so rare, you are early to be testing, so maybe the one test didn't pick it up, but a line IS a line, as long as it showed within the set time, I'd say test with FMU, and if it's negative, wait until the day of your period, if it doesn't come, test. I think you might have gotten lucky this month!! Good luck, let me know how you turn out!! :]
