Charting Question

[TTC74]

Can someone give me their thoughts about my chart? I ovulated early on CD9. Then I had a significant tip drop on 4dpo and 5 dpo. This seems to late for a fallback rise but too early for implantation. Thoughts?

Mid-luteal phase dips can happen in nonpregnancy and pregnancy charts, so it could just be a normal drop due to a rise in estrogen and not an implantation dip.

I will keep my fingers crossed, then. Thanks!
