K.P.
Yes; my first pregnancy, I didn't get a positive until 5 days after my missed period, and it was so faint that I tested the next day and got a negative! Another test the following day had a strong positive, and my son was born about 9 months later. :-) Ironically, both my babies were born at the same day of gestation (39 weeks 2 days), even though I tested a strong positive the first day my period was late with the second one.
