Chart check, 13dpo bbt rise

Kate
This is my first time charting. Started late, but I feel like the O date is accurate or it was 1 day later if anything.
I got OPKs the day after O day (arrived late in mail) and it was near positive and got lighter over the next few days.
I am still getting BFNs on every type of test. 
Is today's temp rise a good thing? Can the cover line be established despite the late start?
Thanks for any input or hope :)
