Hiya, it’s my first month charting with FF.. I know higher temps are supposed to be good, but implantation dips possible too. But this was a big drop at 10dpo. What do we think, am I likely out given when AF due or is there still a chance? Love hearing about similar charts/experiences. I had a vfl with my daughter at 9dpo so not feeling optimistic anymore this cycle. My luteal length is normally 12 days which also suggests period not far away..!
