Please look at my chart. Implantation Dip?

Question

What do you think about my chart? Are there any other reasons that the temp on CD 21 (8 DPO) could be that low? Is there such a thing as an "implantation dip"? What do you think?

(I asked this yesterday, but put a link for the wrong chart, this chart below is my updated chart. Thanks!)

It looks like it could be an implantation dip to me but they don't happen for all women and it's impossible to predict with 100% accuracy whether or not that's what this is until after the cycle is over or pregnancy is confirmed.  Another reason that you could have a temp that low would be that your mouth was open before you woke up and made your temp lower or you had more cold air (say from an air conditioner) blowing on you than usual that particular morning.  But your temps look really good.  You'll have to keep us updated next week when it's test time!  Good luck and baby dust to you!
