lowest temp on chart at 5dpo?! implantation dip or no chance?

Tara
I will start by saying I took this temp about 2 hours earlier than I usually do because my 20 month old woke up in the middle of the night. I had pink spotting 2dpo (I have never spotted pink in my life, I have 2 children) now a hugeee temp dip 5dpo... is it too much of a dip to be implantation?
