Has anyone ever experienced or read anything about a 2 day implantation dip...?

I am too early to be getting AF, but I had a significant drop in temp 2 days in a row.... I of course googled, and I have seen where lots of women have had similar situations (significant temp drop 2 days in a row, too early in luteal phase to indicate af).... So I figured I would reach out to you lovely ladies. Have you ever had any experience with a consecutive 2 day temp drop? Even if not implantation, what was your experience? This whole cycle has been super weird for me. I NEVER have mid cycle spotting, or ovulate this late...
