Where’s my cover line?

Hey! So I know I ovulated around the time this chart shows based on temps and OPKs but because my temps have been so up and down it doesn’t show my coverline. Does anyone have a guess where that should be?

Also I have been taking my temp at the same time everyday so no problem with that. I have been exercising a lot lately which threw my ovulation later than normal.

Last do you think the dip yesterday could have been an implantation dip? I shot back up today! :) fingers crossed. 🤞🤞🤞

Thank you for the feedback!
