Temps! What do you think!?

Hi guys! Just wanted to know what you think of my temps. At 8dpo had a huge drop in temp below cover line. Now at 9DPO I had a huge spike! I was shocked bc I pretty much slept with the fan on me, and felt cold last night. I felt horribly sick to my stomach the night my temp dropped, then it I felt really off throughout the day yesterday. Today I feel much better so far. Having some twinges sometimes semi sharp in both ovaries yesterday and today. Fingers crossed!
