Opinions ??

This month has been a ride for me as my cycles are always regular (28 days) but this one is now on day 35. I had late ovulation (where the arrow is at) which at first I didn’t believe but it makes since now . If I didn’t ovulate late af would be almost about 3 days late now . Yesterday I had light pink spotting (11dpo) when I went to the bathroom . Only one wipe . Af still hasn’t shown . Took my temp this morning and hasn’t risen up to far so not sure if I should consider this implantation dip or not. Hoping you ladies can help me figure out what’s going on as if I did ovulate late today makes me 12dpo .
