I've been having trouble sleeping lately. I've been waking up between 2-3am then falling back asleep and waking around 7am, which is when I temp. This morning I woke up at 2am and then 5:30. I didn't temp at 5:30 because it was too far off from my usual 7. I tossed and turned until 6:45 when I took my temp and it has dropped .3 from yesterday. Should I have taken it at 5:30 to get a good reading? I'm 9dpo and worried that the drop means AF is on her way..
