Please help - 15dpo, high bbt but bfn

Lina

Please help! I think I am 15dpo today (based on temps looks like I ovulated sometime around CD31), but only getting bfns. I started counting my dpos the day my tempts started to go up (CD32). I had lighting crotch on CD41 (10dpo) which I have never experienced before. I am getting so discouraged

but am praying every day to get my BFP.

Any insight or personal experiences would be greatly appreciated.
