They all have 2 lines & the weeks estimator has 3! If it says not pregnant then either you're NOT pregnant or there's not enough HCG for the test to pick up on! Either way cracking it open will not give you a definitive positive so stop doing it & buy a different type of test & retest. I see soooo many posts saying I cracked open the digital & I see 2 lines then when AF shows those same people post how devastated they are BC the digital had 2 lines. Please save yourself the heartache & just throw it away & retest later!!! Good luck & baby dust!!!!
