Elevated temperature for 4 days? at the same time

My temperature has been elevated for the last 4 or 5 days. I don’t really pay much attention during the day, but I notice it’s around 8pm every night. I’m definitely not sick. No symptoms of any kind of sickness. It’s around 99° I usually run around 98.6°

I’m not sure when I ovulated. Im testing negative but with my first two pregnancies I didn’t test with a faint positive until I was on cycle day 44/46. Im on cd 35 today and tested negative yesterday. If im having any symptoms, especially temp wise, wouldn’t I have at least a faint line?

I had hip pain yesterday too tho and a heavy feeling in my uterus area. I can’t remember with my first two if I felt warmer than usual or not. I definitely don’t do that before my periods.

Am I out? Or does this seem hopeful?
