Too early for implantation bleeding?

Bee • 21.07.17 👰🏼❤️🤵🏼 First miracle due Jan '19 💙

How is my chart looking? I’m worried there’s a lot of fall and rises. This is my first month. I take it the exact same time every morning.

Also, the recent dip. I’m assuming it’s too early to be an implantation dip? Please note that even though glow says today is 8dpo I’m actually only on 7 😊
