hi i am really confused with my chart, i have just started temping orally and my temp dropped then rose for 2 days then dropped again but now my CM is all dried up, so do you think it may be becasue i havent had a solid 3 hours sleep? 8-[ day 17 and 18 of my cycle is when my sleep has been disturbed so im not sure whether to discard my temps or not? any help would be appreciated O thanks
