Am I still in??

Please give me your thoughts, I'm desperate lol. So below is my chart and besides the 17th (which was an off temp taking time) I've been over my ovulation cover line, above 98 degrees for 16 days now. I tested Thursday (4 days ago) when I missed my period and BFN. I plan on testing maybe Tuesday? just dont want to be disappointed with another BFN. Do you think I may still have a shot? Thanks in advance ☺
