Hi dolls! Well today I am 6 days past my period due date and I tested tonight at 10 pm, and I got a negative.. I am hoping it is just a false negative but I am not sure.. I'm 18 years old with pretty regular cycles.. About 30 day cycles give or take... I am using Wal-Greens brand pregnancy tests, and I have been peeing all day.. Boobs hurt, cramps slightly for past two weeks, headaches, and above all no menstrual cycle. I am thinking my urine just isn't concentrated enough to pick up the HCG hormone but again, I am just not sure... Has anyone else ever had a negative test and then positive results in the A.M.? I'd love to hear stories..
