Implantation dip?

So I can't open my glow cart, it crashes the app since the update for me, so this is another chart. 3 days ago I had a dip in temp the day before the dip I had a bit of EWCM tinged very very light pink and it didn't continue just a little bit when I wiped.
So could this be implantation dip? I thought I had a slight second line yesterday on a test and today there was nothing so I'm hoping it's just too early, I may be grasping at straws to keep hope up.
So what do you think?
