Ovulation day

Kristen

Could any of you girls who are good at reading bbt charts tell me which day I ovulated according to my temps fertility friend says day 17 but I had another day of ewcm on day 18 which is when premom says I ovulated I was thinking it was day 19 by the way the temps look. Side note cycle day 11 is missing a temp because I woke up with a fever.
