BBT question

Crystal

Good morning! I bought a BBT thermometer b4 my last cycle but I am struggling with using it. My struggle is bc I don't get consistant sleep. I usually pass out for an hr or 2 watching tv w the hubs on the couch and between 11 and 1, use the restroom and I move to bed. then my husband's alarms usually go off from 3 to like 6 every 30 min or less (he sucks most days waking up) and I'm usually tossing to wake him up. Then I am up no later than 7 to get my kids up. On weekends I'm still up.between 11 and 1 to use the bathroom and then up around 645. weekends should be easy but my question is when do I test during the week. I read u should have atleast 3 hours of sleep b4 testing but I dunno if I actually get 3 consistant hrs and when I did b4 when I tried to chart my thermometer would be in a different room so then that didn't work out. thanks for reading and responding
