Last month when I first started tracking, before ovulation my temp was around 36.0-36.5.. then after ovulation it was 36.6-36.9... I’ll show you

This month my temp before ovulation is 36.5-36.7. Why is my temp as high as it was after ovulation last month? Is it normal to differ? Im on CD13 and have irregular cycles as you can see last month I didn’t ovulate till CD34. My period was shorter than normal too, starting with spotting, 2 days of heavy flow then it just suddenly stopped. When I usually have a 5 day cycle. I feel sick, I’ve got a constant sore head. What’s going on?
