Am I doing this wrong..?!

Alright.. so, i'm brand spanking new to BB temping.. I'm actually in my TWW @ 8 dpo.. and only started temping two days ago (i know.. stupid.. but, anyways..)

i've been getting what (comparatively) seem to be really high temps.. 98.74+ the last 3 days.. (98.74; 98.94; 98.76) -i've always known i 'run hot'.. everyone will be freezing and i'm sweating.. but, i have yet to see a chart with consecutive temps >98.6 degrees. Any thoughts/advice would be greatly appreciated. Oh, and yes, i'm temping vaginally.. (TMI) with the thermometer inserted to basically as far is it will go with the screen part not inside 🙃
