9 month’s TTC. Help with chart please :)

LuLu

Hi. This is our 9th month of TTC. Starting to get a little anxious now. Could anyone help analyze my chart? My period is now a few days late. All bfn tests so far. My temp has dropped down, so at this point I’m expecting my period to come any day. The temp is still above the cover line though, so do you think there is still a chance?
