So temps stay high after ovulation and before AF?

My temps have been staying high 98, like 98.5 and up yesterday my temp was 99.8 and no I’m not sick nor feeling sick I just feel warm now!

I had cramps for one day on 6dpo and sore breast and yesterday no cramps (7dpo) just headaches today (8dpo) headache.

My temps are always mid 96 and lower 70s, I’ve never gone up to 98s before
