Another long cycle, but things just got strange

This cycle started 4/28/24. I finally ovulated 6/2/24. The temping goes back further too, but I just added some of it. The chart seemed promising until yesterday where it dropped to just below cover line. I started spotting pink last night and was knew it was AF especially with the temp drop that morning. I wake up on 13dpo and temp was same as yesterdays and my cover line moved down. Went to the bathroom and just wiped even less light pink spotting away. Nothing at all on the pad overnight. I feel like it’s too late for implantation. Tests seem negative. Any ideas??
