BBT first timer - thoughts?

Melissa

This is my first time tracking bbt so I'm still new to it all. My temp spiked yesterday and is high again today along with my CM having an eggwhite appearance. Would it actually be possible to ovulate this early (day12)? My cycles are normally around 5 weeks long and last month I had a blood test confirming ovulation on approx CD30. Could i please get your thoughts on what might cause the temp spike and CM change if it's not ovulation?
