I've continued temping because, unlike most, it gives me a little bit of peace seeing it stay high. That being said, there's always natural variation and your drop doesn't look significant at all to me.
I temped for a week after my BFP, until the girls on here told me to stop it. I did stop, because I think I would have flipped if I saw a temp drop, and I just didn't want to stress. I did take a look at your chart, and that dip is so small, I really wouldn't worry about it at all. Nice implantation dip, by the way!
Re: Temperature drop this morning
I did, and all it did was make me crazy!
Congratulations and put the BBT away for the next 10 months!
