Implantation dip @ 5dpo

[hopingforbean]

Is that even possible?!? Started getting cramps 4dpo that evening right before I left work. Cramps continued all day yesterday (5 dpo). Dip was quite significant and now temp is going back up. I'm confused. Why the dip? Is an ID even possible this soon post O?

the earliest implantation usually occurs is 6dpo. but i am sure some implant on 5 just like some implant 12dpo. just keep temping and see where it goes. I had a dip at 4dpo and then another 6dpo but on 7dpo there was a huge increase in temp.
