So I've just started tracking my bbt but I'm a little confused. So I know it's best to take it everyday at the same time and after 7-8hours of sleep but what if one night you get up in the middle of the night. Like last night I went to bed about 1230 and my husband woke me up about 430 when he got home cuz he was in the mood. I'm in my fertile week (hopefully) so I wasn't going to complain lol. So then I went back to sleep and woke up to go to work around 645. When should I have taken my temp? Should I just have skipped this day since it's probably not very accurate?
