Dpo 17 & bbt at 99.4 and has been elevated..it actually went up and has stayed going up .1 every day since.. took a test late in the day today & got bfn.. I ordered test strips on amazon and got the package when I got home so I just tested late since me & dh were dying to know. Will test again in the morning but I feel like even with it not being morning pee it still should of been a little faint since I’m 17dpo and waited 4 hours to pee. I also had an LH surge during my ovulation
