BBT help

Cl

Hey everyone! I’m new to BBT, and i have a few questions,

Is it possible to still use BBT as a reliable way to confirm ovulation/ monitor luteal phase length IF I’m getting broken sleep thanks to my unsettled toddler who wakes frequently still…

And if i take my temp at different times (maybe 1-2hrs difference) will it matter? I ask because it says online to take temp after at least a 3hr block of sleep; which for me varies 🥲
