Oral vs Vaginal BBT??

Sondra

My chart has been a little inconsistent this cycle doing only oral temps with a BBT thermometer. This morning I decided I'd try an oral then vaginal to compare. My oral was 98.32 and my vaginal was 99.88 !! 😲 Is this normal?? I stuck with 98.32 to keep consistent with my chart but is it normal for vaginal temps to be so much higher!?! Any input is appreciated! Thanks ladies
