FF changed my O day

Mandi • I`m 28 & married to the love of my life. Currently pregnant w/ my 🌈👶🏻. Angel baby 10/16/16 👼🏻 WE ARE HAVING A BOY! 1/1/18 💙
I never have a LP longer then 9 days but today FF changed my O day and now I'm 12dpo. I also never have a cycle longer then 31 days and it's estimating me to have a 35 day cycle. I'm confused but was happy with my temp rise this morning. I took a hpt yesterday morning when I thought I was 8dpo and it was negative, but actually I was 11dpo? Lol! Ugh! How does it look to y'all?
