Is it way too early for implantation?

So I woke up with ovulation pain in the middle of the night ( between the 23rd and 24th) mostly on the left side. Late on the 26th I felt a distinct little prick near the right side of my uterus. I know it sounds insane, but I swear I felt it with my third baby on the 4th or 5th day past ovulation and knew I was pregnant. The next day I started feeling dry and itchy down there, which is not normal for me. I know what a yeast infection feels like and it's not like that, so I looked it up and it could be caused by a progesterone spike, which seems to all line up, but everything says 6-10 days so maybe I'm going crazy. Is it possible that the egg moved through the tube faster and began implanting that early? It sounds insane...
