BBT chart- implantation, period coming, or BFP?

Cass

Hello all, i had a slight drop in temp today as it was previously rising. Could we still have a shot this month for a BFP? Could that slight drop be implantation or period coming? I think it’s too early for period as it says not expected for 10 more days. Should it rise back up tomorrow if pregnant? Help appreciated!!
