Positive opk, ewcm, missed period

Hey ladies,

So I'm currently on cd 35, no confirmed ovulation via oral temping but I don't think oral temping is going to work for me. Day 3 or 4 of ewcm, and got a blazing positive opk. Cycles have been ranging from 28-50 days the last 6 months. Frustrated and curious on anyone's thoughts? Worth taking a pregnancy test or just extremely late ovulation? Photo of current chart as well.
