Is it possible to implant at 5dpo?

It’s later in the day for me (almost 4pm) and I’m 5dpo, I felt a mild but sharp pain on my left side for about 30 seconds and it went away. Felt similar to the pain I felt last time and I ended up being pregnant so I’m assuming I felt myself implant, just wondering if I felt myself implant this time or if 5dpo is still too early. I know usually it happens between 6-12dpo
