11 Dpo Chart

Be

Hi there. I’m new to bbt, but on 7 months ttc. Here is my chart. I’m currently 11 dpo with bfn. I had a big temp dip yesterday followed by a big rise. Has anyone had a similar chart? Is it possible to have implanted at 10dpo and it’s too early to test?

Any feedback / thoughts / well wishes / baby dust is greatly appreciated 🥰
