I'm 2 days late and I've been taken my temperature for 3 days in a row it's been 98.34, 98.34, 98.62. And I'm suppose to be on my period hopefully it's my month this time. And I toke a test and it said negative but I looked at it later and it had two lines but it set there to long so it's invalid but I've went back and looked at all my test before an it's never had a second line so just maybe I'm pregnant I'm gonna test again Friday if I don't start before then..
