Similar bbt chart

Monica

Anyone else have a similar chart that led to a bfp? I could've sworn that I felt implantation cramps 8dpo two days ago when my temp dipped. It was dull/annoying cramps near my left ovary off and on most of the day. Next thing I know, my temp steadily starts to go back up (hopefully it continues). (Sometimes I feel as though my body is trying to produce PG symptoms because I want it so bad) but no symptoms so far. 10 dpo this morning, took a cb digital test (says not pregnant). Any thoughts?
