Hi guys just wondering if anyone can help with my chart I have no idea what is going on this month, my cycles are usually 33 days last month I didn't temp and it ended up at 37 days. This month i had a positive OPK on cd25 and FF put my crosshair on that day but with my temp dropping this morning it's completely removed them. my temperatures have been really low all month. I do have a cold and some nights slept with the window open but I didn't last night I'm just so confused and any advice would be really appreciated xx
