Petrified to think-could this be implantation ?

Chelsea • Miscarriage warrior (x4) Mama to a beautiful baby girl born November 2020.

What do you think? 9 dpo, on cd23. Had implantation in first pregnancy around this time but was very brown. This is ‘light pink’ had a slight heavy tummy feeling today like a dull ache not painful. didn’t have it 2nd time. Both pregnancies ended in MC.
