Glow says my period is not due till 10/24. But my last period was 9/16-9/18. I took a test this monday, and it was negitive. :( my other two apps say I should get my period today! I have been off the pill since aug. 9th. Do you think it's too early to test again? And do you think it matters if you test in the morning or during the day?? Please help me figure it out!! :) thank you!!!!!!!
