Sometimes it can: Take longer than four days for a home pregnancy test to pick up on pregnancy. There may be elevated HCG but it may not be at the level that is required for a + test result. If you don't get your period, you can repeat in a week, using your first morning void. Missed/late period: low body wt, obesity, weight ^ or v, ^exercise, endurance athletics, breast-feeding, stress, illness, eating disorders.
