Help! I don’t know how to interpret my bbt chart!

Morgan

I’m 9 DPO and got a BFN on

FRER this morning but how does my chart look? I temp religiously, but am clueless when I try to tell what it all means. I had very sharp pains on the right side of my right breast that sometimes when to the nipple, but that started 2 DPO and lasted for 3 days. Since then I haven’t felt any symptoms out of the ordinary. I used Clearblue fertility monitor and Preseed this cycle.
