Could this be my bfp chart

Okay here's my dilemma I usually ovulate between CD 17 and 18 mind you I breastfeed anyways I ovulated CD 21 this month but my lethal phase always stays 11 to 12 days today is 10dpo and I almost always get a dramatic dip indicating AF is coming and premenstrual cramps I have gotten either took a pregnancy test today and it was a BFN just curious if this chart could turn into a bfp or of AF is still coming and dip has not showed because of delayed ovulation

Also got full Fern on my saliva test at 9 and 10 DPO
