Help!!!

Im on CD 25 11DPO my BBT went from being 98.6 yesterday to 99.20 today… is this good? Like is that normal? I’m very very new to tracking. I’ve taken a blue dye test 2 of them and from whom I’ve asked they swear they see a vvf line coming in and to just wait a few more days preferably a week to see if anything changes. Aunt Flo is due Monday but so far nothing.
