haha yeah as soon as I posted the link I realised I had the wrong one so I was quickly trying to fix it as you were reading it My LP is usually 13-14 days so I'm not sure why my temp is so close to the coverline - it usually doesn't drop that much until the day of or the day before AF? Still hoping that it goes back up tomorrow and it's just a blip. Just remembered that last night I woke up twice needing to pee (but I didn't want to get up because I thought it was close to my temping time, so maybe the disrupted sleep screwed up my temp?!)
