BBT Chart Opinion! TTC month 6

Bethany

This is my first cycle temping due to ttc for 6 months now and this method was highly recommended! Can anyone look at my chart and tell me what your thoughts are?! I’m confused as to why my temp dropped down to 96.88 and then spiked back up to 97.50 this morning. I tempt every morning at 6:15. My chart used to show that I ovulated on dec 31st but it changed when my temp dropped yesterday. What could this be? Has anyone else had this happen?
