I am not sure! I don't want to give you false hope, but honestly, lots of girls bleed the first month of pregnancy even normal period flow... You seemed to have a lot of symptoms, so I wouldn't ignore the high temps. If I were you, I would wait a couple of days, see what happens with AF & your temp and if nothing changes, test again OR just head to the doctor & have a blood test to make 100% certain you are not pg.
Here's a little note, my mom had bfn's with my brother for FIVE months!!! Even at the doctor's office! So, they finally gave her medication to try to make her start her period and she insisted on an ultrasound... she found out that she was pregnant and that it was a boy in the same day... crazy. My point in all that is never ignore your own body and your own instinct! Had my mother not demanded an ultrasound, who knows how long it would have been before she found out or how long she would've taken the medication they gave her (which is not safe during pgnancy).
